Vacuum system control
Vacuum Unit
Vacuum unit (VU) is a set of vacuum pumps and gauges. KAGRA has a vacuum unit every 100m. So the total number of VUs is 60.
Each VU has ion-pumps, an ion-gauge,a convectron, a turbo molecular pump (TMP), a fore-line pump. The TMP and the fore-line pump will be stoped after initial pump down. So these are not under remote monitoring.
