Helium Cryogenics
in TRIUMF In TRIUMF, 500 MeV cyclotron is
used as a proton beam source for
most of the experimental facilities.
Cyclotron utilizes cryogenic
pumping to achieve high vacuum
inside of the tank. Upgrade of the
LN2 circuit is considered as a
future upgrade to conserve on
LN2 budget. Spare RSX
compressor was purchased.

Cyclotron tank, Linde 1630 helium refrigerator, operational and spare compressors
Linde TCF50 helium refrigerator, main compressor, storage tanks, upgraded ORS
ISAC cryogenic system is
based on two TCF50
coldboxes. In 2013-2015
oils removal skids of both
compressors were
upgraded. Additional third
coalescer was installed to
eliminate oil migration
issues that caused few
interruptions of operation.
ISAC Cryogenic System
Helium Recovery System / UCN Liquiefier
TRIUMF used to purchase
500,000 CAD worth of
liquid helium for its
experimental facilities.
None if this was recovered.
In 2013, helium recovery
facility was installed,
conserving operational
budgets. Helium storage bag, high-pressure compressors, high-pressure cylinders, Linde 1610 compressor and liquefier
Air Liquide coldbox with dewar, e-linac cryomodules, burst disk event, compressor building (image from 3D scan)
ARIEL cryogenic
system is based on Air
Liquide HELIAL LL
coldbox. The project
caused many minor and
major upgrades of
cryogenic infrastructure,
including upgrades of
TRIUMF’s LN2 system
in 2012-2015.

TRIUMF’s Cyclotron Cryopumping System
Over 40 years of operation,
TRIUMF’s capacity of helium
cryogenics significantly
increased.
Starting from 100W of
cooling at 4K in 1970s it
grew ~25 times up to almost
2.5 kW with new helium
coldboxes installed for
Cyclotron cryopumping,
ISAC SC linac, helium
recovery and ARIEL electron
SRF linac.
