Description

Injector Drive Laser System information Request for Information - DO NOT SEND ANY PRICING INFORMATION - THIS IS A SOURCES SOUGHT POSTING - PROVIDE YOUR CAPABILITIES TO MANUFACTURE THIS SYSTEM. LCLS-II Injector Drive Laser System Introduction The Linac Coherent Light Source (LCLS), an X-Ray FEL project of the SLAC National Accelerator Lab of Stanford University, requests budgetary, schedule and technical information for a laser system for the LCL- II Injector. SLAC had successfully built and commissioned the LCLS-I, that had been fully operational user facility since 2009. Now SLAC is planning to build the second - more advanced Linac Coherent Light Source - LCLS-II. Information about the LCLS can be found on the following website: https://portal.slac.stanford.edu/sites/lcls_public/aboutlcls/Pages/default.aspx The essential parts of the LCLS machine are the UV Drive laser and the IR Heater laser. UV Drive laser will be used to illuminate a photocathode located inside a high field RF gun in order to generate a high quality electron beam. The IR Heater Laser will be used for suppressing micro-bunching instabilities in the Injector electron beam. Both lasers will be placed in the laser room located next to the beginning of the SLAC two-mile linac (Sector 0), and their beams will be delivered through the conditioning, transport and launch systems to the Injector - respectively to the RF gun and to the Laser Heater region. The IR part of the UV Drive laser and the IR Heater laser are the subject of this procurement. These two lasers should be identical. Procurement Process The LCLS II drive laser and heater laser will be purchased as a single procurement. The process begins with this release of Request for Information (RFI) followed by a Request for Proposal (RFP) and the Award of Contract. The present RFI is intended to identify potential vendors to supply the drive laser and heater laser. SLAC will select 3-4 vendors to participate in the RFP process which is expected to be released in January 2016 with a bid due date 4 to 6 weeks later. The Award of Contract will occur upon receipt of funds in March of 2016. The first laser should be delivered by January 2017, the second -could be delivered couple of months later. Laser Architecture We anticipate that the laser architecture will consist of a MOPA (master oscillator power amplifier) type using a standard CPA (chirped pulse amplification) scheme. The oscillator source needs to be synchronized (phase-locked) to an external (SLAC supplied) RF source. The final high power IR beam will be produced via high gain, broadband amplification of phase-locked oscillator pulses through a fiber amplifiers chain of the vendor design. However, the detailed laser system architecture is determined by the vendor and other technical approaches are encouraged. Laser Specifications The Specifications for the laser oscillator and amplifier are described in the Tables 1 and 2. SLAC will accept the information either on only subsystem (only oscillator or only amplifiers) or on the whole system. However the vendor who is providing the amplifier is responsible for the integration of the system. Table 1. The laser system output (Of the final amplifier) specifications Parameter Value Comments IR laser output center wavelength 1030 nm Minimum average IR power 50 W Minimum Pulse Energy 50 µJ Maximum Pulse repetition rate* 0.9286 MHz Pulse duration (FWHM)** <400fs Adjustable out of Fourier limit Minimum output pulse-to-pulse energy jitter (RMS) 0.25% Pulse energy stability over 24 hours <0.5% Minimum pointing stability (RMS) 20 µrad Collimated free space output M2 <1.2 Ellipticity >0.9 Output beam spatial shape Gaussian No ripples Output beam temporal shape Gaussian No ripples Polarization ratio 100:1 Fixed in direction Nanosecond pulse contrast <1% *The output beam repetition rate frequency should be variable: Any integer sub-multiple of the oscillator rep-rate should be available. **Fourier limited pulse duration should be close to 400 fs, but by adjusting the compressor length (increase of the linear chirp) we should be able to lengthen remotely the pulse duration to up to 2ps. The laser system design should allow adjustments of the stretcher and compressor by a user. Table 2. The laser oscillator specifications Parameter Value Comments Oscillator output central wavelength 1030 nm Average optical output power >100mW Pulse duration >250fs Pulse repetition rate* harmonic to 1300/1400 (0.9286) MHz Option 1 92.86MHz Option 2 46.43MHz Option 3 37.14MHz Collimated free space output M2 <1.2 Maximum timing jitter relative to RF (RMS) 100fs In the bandwidth 100 Hz - 10 MHz Amplitude noise <0.1% rms During 1 hour Pulse energy stability <0.5% over 24 hours Synchronization The oscillator will be synchronized to the SLAC RF Requires option: Built-in piezo electric transducer (PZT) and internal photodiode. In addition to PZT an option for coarse (slow) cavity length adjustment should be implemented. Control of PZT and slow cavity length control are required. Phase locked loop bandwidth >500 Hz Residual timing jitter relative to reference (RMS) <100 fs DC - 10 MHz The output of the oscillator is used: 1)as seed source for a high power fiber amplifier system, 2) to derive a signal for timing synchronization and 3)for temporal shape diagnostics **(cross-correlator) * Decision about what option to buy will be made before the RFP (Request for Proposals) will be issued. ** Because some of the oscillator pulses will be used for building a temporal profile diagnostic tool, we should have access outside the laser amplifier enclosure to a small portion (defined by the vendor) of the oscillator pulses picked anywhere (defined by the vendor) before the stretcher. The option to have that oscillator output beam for our diagnostic tool compressed to a shorter pulse duration of <50fs should be included in the proposal. Other System Requirements The laser system should operate with external or internal triggers at any repetition rate up to maximum. The laser system should be able to provide signals for the SLAC controls/timing interface. The details will be specified in the RFP. It is essential that the drive laser system reliably operate for long periods of time. The goal is stable operation, 24 hours a day for several weeks without interruption. Therefore the design should include features that help to increase the lifetime of the system with greater than 5000 hours average time between failures. Diodes lifetime should be more than 1 year for 24/7 operation. The size of the whole system should not exceed 2' x 8' (60 x 250 cm). Integration and Delivery The vendor is required to complete full system integration and integrated testing prior to shipment. After shipment the vendor should perform the system installation at the SLAC site, repeat the fully integrated testing and provide training for the SLAC personnel. Warranties and Service Contracts The vendor will provide their standard warranty for the full laser system. In addition the vendor must provide a technical service contract for a period of at least one year following the laser system installation at SLAC. It is also to be renewable beyond the one year period. The detailed requirements to warranty, service contract and customer support will be described in the RFP. Laser safety requirements The laser system must be certified to meet U.S. FDA laser safety requirements for laser products and have associated certification labels. The laser system must comply with either 1) 21 CFR1040.10 <http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?FR=1040.10> and 21 CFR 1040.11 <http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?FR=1040.11> requirements or 2) FDA Laser Notice 50 <http://www.cdrh.us/pdf/laser-notice-50.pdf> requirements. Electrical safety requirements Laser systems' electrical equipment should be certified and listed for use in the US by a Nationally Recognized Testing Laboratory (NRTL) whenever possible. NRTL-listed laser systems that are used within the listing agency and manufacturer requirements are acceptable for use at SLAC without any additional electrical safety inspections. Electrical safety requirements for non-NRTL equipment should meet the following requirements (Note: these requirements are especially important for flashlamp-pumped laser systems): i. Personnel must not be exposed to any electrical hazard 50 volts or greater (AC or DC) during normal system operation. Enclosures that contain exposed hazardous voltages must be accessible only by use of a tool or a key. ii. There must be no exposed energized parts 50 volts or greater (AC or DC) when the laser head cover is removed. iii. All connectors containing hazardous voltages (50 volts or greater, AC or DC) must be touch safe (i.e. shall not present a contact hazard to the worker). This is true even if the system is interlocked to automatically de-energize a circuit when disconnected. iv. Line voltage fuses, if provided, must be NRTL-listed for the US, and: • If line voltage is 120 VAC, the "hot" wire must be fused; a neutral fuse is optional • If line voltage is >120 VAC, both "hot" wires must be fused • Fuse holders must be labeled with fuse rating v. All internal wiring insulation must be rated for the voltage involved. vi. Internal wiring of different circuit voltages must be separated unless the insulation rating of each grouped wire exceeds the maximum circuit voltage within the group. vii. AC mains power connection must include provisions for an equipment grounding conductor. For cord-and-plug connected equipment the cord and plug must be of the grounding type. viii. All non-current carrying exposed metal must be bonded to the equipment grounding conductor. ix. Capacitors must have bleeder resistors or automatic discharge devices. The time required for a capacitor to discharge to safe voltage (less than 50 volts) shall not be greater than the time needed for personnel to gain access to the capacitor terminals, but in no case should exceed five minutes.
