From R. Michaels The following data appears as text data in the datastream as event type 131. This information is up-to-date as of June 8, 97 Here are BPMs in the datastream IPM1C10.XPOS IPM1C10.YPOS IPM1C12.XPOS IPM1C12.YPOS IPM1C14.XPOS IPM1C14.YPOS IPM1C16.XPOS IPM1C16.YPOS IPM1C18.XPOS IPM1C18.YPOS IPM1C20.XPOS IPM1C20.YPOS IPM1C98.XPOS IPM1C98.YPOS IPM1H01.XPOS IPM1H01.YPOS The following are BPMS near the target IPM1H03A.XPOS IPM1H03A.YPOS IPM1H03B.XPOS IPM1H03B.YPOS A variable without the "XPOS" or "YPOS", e.g. IPM1H03A, is an approximate beam current.

The data are of the form KEYWORD VALUE where keyword describes the variable and value is its numerical value. A value of "-+" means the variable failed to readout. Note that one receives alternative event 131 of accelerator information (the first group) and hall A controls information (the second group). Each of these come every 30 sec. A smaller group of the "most important" signals consisting of IPM1H03A and 3B XPOS and YPOS, and hac_bcm_average comes every 4 sec. =============================================================== Fri Feb 28 14:35:23 EST 1997 IPM1H03A 36.8919 IPM1H03A.XPOS -2.864 IPM1H03A.YPOS 0.476 IPM1H03B 21.8758 IPM1H03B.XPOS -1.607 IPM1H03B.YPOS -0.44 IPM1C10 17.417 IPM1C10.XPOS -1.722 IPM1C10.YPOS 1.634 IPM1C12 40.034 IPM1C12.XPOS 0.607 IPM1C12.YPOS 0.483 IPM1C14 16.5552 IPM1C14.XPOS 1.466 IPM1C14.YPOS 0.912 IPM1C16 27.1533 IPM1C16.XPOS 1.644 IPM1C16.YPOS -0.352 IPM1C18 15.0698 IPM1C18.XPOS 1.911 IPM1C18.YPOS 0.588 IPM1C20 40.9122 IPM1C20.XPOS 0.437 IPM1C20.YPOS 1.155 IPM1C98 -+ IPM1C98.XPOS -+ IPM1C98.YPOS -+ IPM1H01 10.5792 IPM1H01.XPOS -1.975 IPM1H01.YPOS 0.958 IBC1H03AAVG 1.7094 MBSY1C_energy 845.001 Sat Jun 7 13:41:37 EDT 1997 HacE_Q1_DF853:AD8 897.785 HacE_Q1_LS450:FIELD? 0.2957 HacE_D1_HP3458A:IOUT 399.261 HacE_D_NMR:SIG -+ HacE_D1_NMR:SIGLCK L HacE_Q2_HP3458A:IOUT 513.691 HacE_Q2_LS450:FIELD? -0.2683 HacE_Q3_HP3458A:IOUT 475.12 HacE_Q3_LS450:FIELD? -0.23621 HacH_Q1_DF853:AD8 727.685 HacH_Q1_LS450:FIELD? 0.009425 HacH_D1_HP3458A:IOUT 329.295 HacH_D1_NMR:SIG 0.35909 HacH_D1_NMR:SIGLCK L HacH_Q2_HP3458A:IOUT 416.377 HacH_Q2_LS450:FIELD? -0.20677 HacH_Q3_HP3458A:IOUT 384.802 HacH_Q3_LS450:FIELD? -0.17209 hac_bcm_average 6.00315 hac_unser_current 0.5175 hac_bcm_dvm1_current 6.2348 hac_bcm_dvm2_current 5.77151 Sun Mar 23 13:17:42 EST 1997 IPM1H03A.XPOS -0.327 IPM1H03A.YPOS 0.521 IPM1H03B.XPOS -0.214 IPM1H03B.YPOS 0.595 hac_bcm_average 5.30796This page maintained by rom@jlab.org
