[Dsg-rich] RICH recovery

Hello,


We have noticed that regularly (almost on a daily basis) that the RICH recovery procedure is used.


Previously, Valery has told us that the recovery procedure does the following:

  1.  LV off
  2.  LV on
  3.  ssh rich4
  4.  rich_init


With the frequency of reboots of RICH DAQ, we are concerned that the reboots will lower the lifespan of the MAPMTs and readout electronics. How many times could the system be reinitialized without the chance of failure?


Best regards,

Tyler
