HRC Higher-Level Sequences

Switch Operational HRC-I to Operational HRC-S


This higher level sequence takes the HRC from a state with the HRC-I MCP HV on and at the operational level to one with the HRC-S selected as the detector in use and the HRC-S MCP HV on and at the operational level.


The HRC-S MCP HV must not be ramped up if the HRC is in a region of high radiation (see HRC-R-002) or if the detector housing pressure is greater than 10-5 torr (see HRC-C-002).

The stored command sequence to turn on the HRC-S MCP HV must be in the enabled state. If it has been disabled in response to an EPHIN trigger, the radiation environment must be verified as safe before we can proceed. The stored command sequences to ramp the HRC-I MCP HV up and down must be disabled.
