op03:

HRCOBS Configuration

Description:

Notice that since we expect to use default settings for most observations, this higher-level procedure will usually only send commands to the HRC if there is a detector change (HRC-I to -S or HRC-S to -I).

Cautions/Restrictions:

Procedure

• If the HRC detector housing door is NOT OPEN
  • If HRC shutters are not at the "Home" position
    • Home +Y Shutter (home_posy.html)
    • Home -Y Shutter (home_negy.html)
  • HRC Door Open (door_mostly_open.html)
• If this observation uses a different detector than the current detector
  • HRC MCP HV Off (hcp_hv_off.html)
  • Terminate SCS #91 - HRC Dither Control
  • If this observation uses the HRC-I
    • Set HRC-I Unique Defaults (i_unique.html)
    • Disable SCS #88 "HRC-S MCP HV Ramp-down"
    • Disable SCS #90 "HRC-S MCP HV Ramp-up"
    • Enable SCS #87 "HRC-I MCP HV Ramp-down"
    • Enable SCS #89 "HRC-I MCP HV Ramp-up"
    • HRC-I MCP HV On - SCS #92 (i_mcp_hv_on.html)
  • Else we use the HRC-S
    • Set HRC-S Unique Defaults (s_unique.html)
    • Disable SCS #87 "HRC-I MCP HV Ramp-down"
    • Disable SCS #89 "HRC-I MCP HV Ramp-up"
    • Enable SCS #88 "HRC-S MCP HV Ramp-down"
    • Enable SCS #90 "HRC-S MCP HV Ramp-up"
    • HRC-S MCP HV On - SCS #93 (s_mcp_hv_on.html)
• If the detector is not currently configured with the default settings
  • If the shutters are not at the home position
    • Home -Y Shutter (home_negy.html)
    • Home +Y Shutter (home_posy.html)
  • If the current detector is the HRC-I
    • Set HRC-I Unique Defaults (i_unique.html)
  • Else the current detector is the HRC-S
    • Set HRC-S Unique Defaults (s_unique.html)
• If this observation does not use the default settings
  • If non-default trigger threshold
    • Send command 2LLDIATH with 2LLDIAT1 = TRIGGER_LEVEL
  • If non-default range switch value
    • Send command 2RSRFAAM with 2RSRFAA1 = RANGE_SWITCH_LEVEL
  • If spectroscopy mode is "IMAGING"
    • Send command 2SPIMASL
  • If anticoincidence vetoing is enabled
    • Enable Antico Veto (antico_veto_en.html)
  • If width vetoing is enabled
    • Send command 2WDTHAEN
  • If non-default width threshold
    • Send command 2WDTHATH with 2WDTHAT1 = WIDTH_THRESHOLD
  • If ULD vetoing is enabled
    • Send command 2ULDIAEN
  • If non-default ULD level
    • Send command 2ULDIATH with 2ULDIAT1 = UPPER_LEVEL_DISC
  • If center blanking is enabled
    • Center-Blank (c_blank_en.html)
  • If edge blanking is enabled
    • Edge-Blank (e_blank_en.html)
  • If +Y shutter is not at "Home"
    • Move +Y Shutter to Requested Position (shutter_posy.html)
  • If -Y shutter is not at "Home"
    • Move -Y Shutter to Requested Position (shutter_negy.html)
• Activate SCS #91 (HRC Dither Control)

Revision 1.5 1999/04/21 13:31:57 juda

marked as Approved

Revision 1.4 1999/03/03 21:34:33 juda

changed links for files with name changes

Revision 1.3 1998/11/18 17:16:31 juda

moved "MCP HV Off" and "Terminate SCS#91" out of detector specific sections

Revision 1.2 1998/10/15 20:44:30 juda

replaced calls to pages for switch HRC-I to HRC-S and HRC-S to HRC-I with the necessary explicit line. This removes the MCP HV ramp-up activation and allows SCS #91 to do the ramp-up
