Info on the Oxford Cyberstar X1000 detector electronics and NaI detector head.
Also find attached a doc from CMC-CAT about dead time.
For Undulator A setting of 7.5 keV (best guess of actual photon energy is 7.4 keV):
- HV = 930V
- Gain = 4 (local), 40% (remote) - 0.3 us peak shaping time
- LL = 1 (local), 10 (remote)
- UL = 3.2 (local), 32 (remote)
- Mode = n
- Signal Out -> Scope
- Window Out -> Detector, Correlator, ... use Pulse Research Labs TTL splitter for fan-out
Note: Do not use 300 ns shaping time as it gives spurious spikes and could be because of the TTL line driver we are using. It is better to use 500 ns.
Note: Settings for 3rd harmonic (22keV)
- HV = 930V
- Gain = 2 (local), 20% (remote) - 0.5 us peak shaping time
- LL = 3 (local), 30 (remote)
- UL = 5 (local), 50 (remote)
- Mode = n
