- Assembled exhaust line flexible hose and fittings as per ISK0529 Rev D then leak checked: 1.4E-1 Torr test port pressure, 1.1E-7 atm-cc/s leak rate, no response to helium spray at both ends of flexible line (all vacuum fittings purchased from Kurt Lesker under Requisition #1046936)

- Connected exhaust of SMP vacuum pump to nuclear ventilation duct using flexible hose assembly as per ISK0529 Rev D

- Installed convectron gauges at pump inlet as per ISK0529 Rev D 

- Installed TCS plug block (IRH1646) in SMP

- Connected plug block vacuum port to SMP pump using flexible corrugated hose

- Connected SMP:CG1 to portable pressure display: ~700Torr 

- Turned on SMP:MP1 at 4:17pm, after approximately 25 minutes was down to 75 Torr, at 1hr 40 minutes was 90mTorr, left pumping over night

 

 

July 4:

- Pressure at 4mTorr at 8am, will leave pumping longer to see if it gets any lower

- Submitted Work Request #5239 to PLC Controls for wiring of the pump and convectron gauges and integrations with EPICS
