Vacuum

The readings from the vacuum gauges either side of a given experiment are available via the views:

V_L3_VACUUM

V_ALEPH_VACUUM

V_OPAL_VACUUM

V_DELPHI_VACUUM

/* Vacuum pressure readings along straight section around IP in */

/* 10**-10 torr averaged over subsections of the straight section */

/* P = measured with ion pumps */

/* G = measured with vacuum gauges */

The views are on a table called M_VACUUM which will have an entry in m_timestamp_table. The update rate will be slow.

What do the names mean? Example:

VAC_P831 Q18 to Q11.L

VAC_P839 Q11 to Q05.L

VAC_G845 ZL2.L

VAC_P847 Q02 to QSC.L

VAC_P851 QSC to Q02.R

VAC_G853 ZL1.R

VAC_P855 ZL2.R

VAC_P862 Q18 to Q11.R
