[Halld-offline] Offline Software Meeting Minutes, April 29, 2015

[Richard Jones]

Hello Mark,

>From the minutes, "

   - *HDGeant now uses RF period in CCDB*. Paul checked in a change such
   that HDGeant will look up the bunch frequency from the CCDB when simulating
   electromagnetic background. The current setting in the database is 499 MHz.

I am not sure which change that refers to, but yesterday I checked in a
change to HDGeant that fits this description. The current setting in the
database is close to 250 MHz, not 500 MHz. This is what I see when I run
hdgeant with a RUNNO set to a number in the current range, eg 2933:

 settofg: beam_bucket_period_ns set to    4.0080161
