1. EN-CV interventions during EYETS for PS and PSB 2016-2017

2. Highlights
The manpower is common for all the machines of the PS Complex and for half of the LHC.
Time constraints must be sent to the contractor → please send your specific request for water.
Preliminary plan as been established.

3. Activities for the EYETS
Normal yearly maintenance
Example for the cooling circuits:
Emptying the primary circuits and cleaning of the cooling towers
Repairs
Necessary maintenance (filters, belt, greasing, …)
Instrumentation check / calibrating
Bugs fixing
Corrective maintenance
