progress report
2010
12.500 litres (corresponding to more than 230 hours of operation) have been produced by the Linde liquefier,
while the remaining 10.700 litres have been purchased to compensate for the system losses. The resulting
average recovery efficiency is estimated to be about 53.8%, less than that recorded in 2009 (when about 65.5%
was recovered). Such a low recovery efficiency is partially due to some demanding experiments carried out by
the Superconductivity laboratory, which may occasionally require considerable amounts of refrigerant to be
evaporated in a very short time, thus making both the capacity of the gas bag (5 m 3 ) and the throughput of
the recovery compressors (80 m 3 /hr), inadequate. Moreover, during about six months of 2010, the recovery
system was operating with only one of its two compressors, due to maintenance being performed in turn on
both machines, as it is necessary after 15.000 hours of operation. This resulted in a reduced recovery
throughput of only 40 m 3 /h and therefore in losses larger than usual.
Data from independent gas counters in the (separated) recovery lines of each user allowed, throughout 2010,
the different recovery efficiencies to be disentangled by FTU and Superconductivity laboratory. As a matter of
fact, by comparing the amounts of liquid helium delivered and of gas recovered by Superconductivity
laboratories and FTU it is possible to evaluate the percentage of total helium lost by each user.
