- Description
- SOW RFI Brand name or equal: Hamamtsu Corporation Product Number: R7600P-203 Description: P-type of R7600U-200 with UV Window Quantity 10 Our group performs a variety of quantum computing and quantum simulation experiments using trapped Be+ and Mg+ ions. An essential part of all of these experiments is readout of the internal electronic state of the ion. Readout of the quantum states of the ions is accomplished by collecting fluorescence photons from the ions and detecting them with a photomultiplier tube (PMT). This fluorescence is a very weak signal; typically only 20 to 100 photons will reach the PMT. The fluorescence is in the ultraviolet at 280 nm (Mg+) and 313 nm (Be+). The new PMTs must be compatible with our existing experimental infrastructure. Our current infrastructure is: • dark boxes will accommodate head-on PMT 30 mm square or smaller • PMT sockets with integrated voltage dividers (Hamamatsu E5996) • voltage bias circuitry (800 VDC, low noise) • readout electronics (Hamamatsu C9744 counting modules) PURPOSE: To improve our quantum readout capability and to support essential aspects of our experiments, we require PMTs with maximum quantum efficiency at 280 nm and 313 nm (to improve detection of the few available photons) and very low dark current (to reduce the dark count background). These capabilities will allow higher fidelity qubit readout in shorter periods of time. TECHNICAL SPECIFICATIONS: We require a total of eleven (10) photomultiplier tubes (PMTs). The PMTs must comply with the following specifications: • Quantum efficiency greater than 34% at 280 nm and 38% at 313 nm • Spatially uniform photocathode sensitivity (within 10% across full area of cathode) • Gain of 10^6 or greater • Anode dark current below 0.5 nA • High speed operation - rise time below 2 ns, transit time below 10 ns. • Magnetic field sensitivity - must have relative anode output better than 80% of zero-field anode output for magnetic fields below 5 mT (most sensitive PMT axis). Delivery: 14 Weeks ARO
