As a difference with respect to the present layout, the Link Valves shall close automatically to protect the vacuum level reached inside tubes/towers (active safety loops)
_PR suspension can be dismounted? If not...
_ bench towers height /gas load shall increase, difficult to use ‘helicoflex’ - traps

3. Station Turbo_PR or Turbo_SR, preliminary
Tower links
Automatic valve with position indicator
Turbo, to be purchased, normally with controller on board, rs232 necessary to visualize parameters PE
2 gauges, to be purchased, normally same to the ones we have, but not necessarily PI
Automatic valve with position indicator
To the remote scrolls

4. Ions, preliminary
Could be grouped near IB, DT, MC and also distributed (An option is to remove one TSP pump (P32) and put one Ion pump on that port). In alternative two additional Ion groups could be installed on two links, for instance near BS.
Tower links
Manual valve with position indicator
2 Ion pumps, 1 controller , for instance Varian starcell 500 +
DUAL per pompe ioniche:

8. Cryotraps 2of2, preliminary
Cryotraps 2of2, preliminary. Cryogenic controls, pid for level control and external tank
Pressure 1
Some temp readouts to be acquired. The controller will have relays to close also valves in case of high temp alarms

Automatic valve to be linked to the temp control
existing large valve, to be linked to the temp control
Pressure signals (2) , normally 4-20mA, to be recorded
Pressure 2
PID level regulator to be read by remote, normally with a few low level output or rs232 or other.
Could retransmit the level and valve status
Level 1

LN2
Electronics driver to be read by remote, normally with a few low level output or rs232 or other
PID
Electronics driver to be read (tbc) by remote, normally with a few low level output or rs232 or other

Comments:
add readouts of LN2 tanks pressures
Automatic proportional valve, with position indicator, tbc

9. Double oring on bottom flanges.
From the point of view of control system, it is one additional gauge per tower (pirani) PI
CF16, to be metal sealed in case of helicofles
Double orings on end tower viewports too

Integrate RGAs? Normally not convenient, but currently use remotizers/rs485 and data storage is not well organized
