[Halld-tracking-hw] New preamp

[Fernando J. Barbosa]

Hi Naomi,

It looks good. It looks like you have too much charge at 2200V as the 
pulses are getting noticeably distorted. Maybe 2100V should be OK but I 
suggest you get a new ADC spectrum, a plateau and determine the actual 
chamber gain.

Thanks and best regards,
Fernando
