•
9 helium tanks of 80 m3 each, dedicated to the
6kW Linde cryoplant for GHe storage
12 helium tanks of 250m3 each, dedicated to the
18 kW Air Liquide cryoplant, for GHe storage
A 25000 liters dewar for LHe storage
A mobile 10000 liters dewar for LHe storage
•
•
1 dewar of 50000 liters dedicated to the 6kW
Linde cryoplant and the HP purification system
(+ infrastructure SM18)
1 dewar of 50000 liters dedicated to the magnet
test benches
2 dewars of 50000 liters dedicated to the 18kW
Air Liquide cryoplant and BA7.
• All warm return gases (pure) can be sent either to the 18kW Air Liquide plant or to the 6kW Linde
plant.
• The return gases are analysed for impurities (air/humidity) and can be sent to the balloons if
necessary (not all return gases – flow too high)
HP Purification system:
• 5 balloons of 80 Nm3, total capacity of 400 Nm3
• 3 Burckhart compressors with 100 Nm3/h at 200 bar each
• 2 HP purificators of 200 Nm3/h at 200 bar each
LP Purification system:
18 g/s on-line purification system (freeze-out) at the outlet of the warm pumping unit
Clients




The magnet test benches (Dewar-PM18)
The RF-cavities and modules (Dewar-PM18)
The 1.8K Cold Compressor Unit – test facility at BA7 (PM18)
STRING2 (a full-size model of a regular cell of an LHC arc)
(Linde)
 A test station for testing High Temperature current leads 600A and
13kA (Dewar-PM18)
 The GREC experiment, Grands Reynolds Cryogéniques (Linde)
The clients take Liquid Helium from the 25000 liters dewar at 4.5K and send back
pure gaseous helium - cold or warm - to the low pressure side of the compressors of the cryoplant
(18kW/6kW)
or impure to the balloons.
The client can decrease the temperature to 1.8K by pumping on the helium bath.
A refrigeration capacity of 360W @ 1.8K is available via a warm pumping group in series with a onestage Cold Compressor Unit.
The outlet of the pumping group passes an « on line low pressure purification system » and is sent back
to the low pressure side of the compressors.

Non Conformity Report ALLS - summary
Coldbox 6kW Linde:
STRING:
20 Beeps:
5 utility-cuts resulting in production-stop
18 Beeps:
12 for HTS OFF
6 due to problems STRING (e.g. errors in control)
-> none of them in Bonus-Malus-file as they were
not resulting in a production-fault for STRING
For example: powercut with as consequence
blow-up of several balloons
1 cryogenic problem resulting in a production-stop
4 cryogenic problems in planified period (cooling
down or warming up of STRING)
4 due to cold coming from STRING (turbines
stopped)
2 due to pure gas storage (MP) too high
1 due to pure gas storage (MP) too low
3 due to stop of CP2 only (no production stop)
Bonus-Malus-file:
5 utility-cuts;
1 cryogenic problem with beep
5 cryogenic problems without beep (during
working hours)
For example: Turbine 4 broken
