LIGO Document E1600260-v1
- Add a 4.7pF capacitor into C25 of the ITM ESD Driver Main Board in the high-voltage bias section of the circuit.
This capacitor is there to ensure stability of the HV stage, and to preclude a ~175kHz oscillation that has been seen on some units.
Capacitor Manufacturer: American Technical Ceramics
Manufacturer’s Part Number: 800B4R7BT500XT
