Re: HV board / ASIC
Hi Fernando,

Yes, we redid the Fe-55 measurements with the %2 interposer and could not
get rid of the 2nd peak. We also saw that comparing with the normal
interposer we lose linearity for HV above 1750~V. The
results are in GlueX-doc-1079-v8, we see a gas gain of 1.5.10^5.
Cheers,
Yves
