Ramped voltage on TM2 up to 30kV with no problems. Bias current is at 29uA, same as original TM2 bias current (see archiver for ITE June 15th, before protons) and similar to 31uA right after protons went off on Aug. 6.
TGHT=0A
TBHT=0A
BIAS V=30kV
BIAS current = 29uA
EZL V= 15kV
EZL current= 51uA
EE V= 1kV
EE current= 0.952mA
IG1= 8.6e-7
protons=0
This seems ok despite poor electrical checks showing 300 MOhm resistance between HV and ground. These values indicate a resistance of 1 GOhm. Let's see what happens when protons are on.
For future (optimistic) reference when testing protons:
BIAS=35kV, 35uA
EZL-17.5kV, 60uA
BIAS=38kV, 37uA
EZL=18.5kV, 63uA |
