Dual MCPs testing(Possible to load 3 MCPs)
3 high voltage (0-5kV)DC power supply
pA current meter
A new EMWCD submitted in Oct 10 and approved in first week of Jan 11
HW design for MCP Gain test
Electrical connections
Shielded UV source for electron generation
Drain resistors box
Photograph of MCP(s) holder assembly:
MCP 114 is loaded on the holder and will be tested

R=60M
System capabilities:
• Current vs. Voltage (I-V)
• Resistance vs. Temperature (R-T) (Thermal coefficient , activation energy)
• Resistance vs. Time (R-t) @ fix HV
• Gain vs. voltage
• Long term stability under scrubbing condition
• Two optical windows (possible to get thermal imaging with CCD)
