PMT simulator - RFQ

[gkasprow]

6-channel PMT simulator in DI/OT form factor Features

• charge calibrator principle
• 6 outputs (we need 2 cards to emulate 12-channels)
• 0...-5V amplitude
• multi-hit ability (2 pulse pileup)
• EEM and DI/OT interface (16 x LVDS)
• 16bit fast DAC for each output
• MCX outputs

Having 16 LVDS channels controlled with 1ns granularity (or even better when running ARTIQ at 160MHz) we can assign control lines in the following way:

0..3: SPI DAC (same family as in Zotino but 16 channel: AD5361); we will re-use Zotino ARTIQ driver 4..9: main pulse trigger 10..15: second pulse trigger (pileup simulation)

The first 6 DAC channels will define the main pulse energy, next 6 channels will define the second pulse energy

this is possible calibrator; use very low Qg MOSFET like CSD15380F3 and simulate it first

XP231N0201TR-G and EPC2038 are another transistors to consider
