The ultra-stable measurement solutions based on liqiud Helium
systems
This system is based on a liquid Helium bath
cryostat and has been optimized for highest
stability. This system enables e.g. ultra high
resolution imaging using Scanning Tunneling
Microscopy (STM) or long-term investigations
of single quantum dots over several weeks. A
large variety of microscopy and probing heads
cover a broad spectrum of measurement tasks.
Superconducting magnets up to 15 T are available
with this system.
Three LTSYS-He systems are available:
LTSYS-He4:
Dependent on the pumping system,
temperatures down to 1.5 K can be achieved.
With an additional heating stage the temperature
of the sample can be swept up to 70
K. A Variable Temperature Insert (VTI, optional)
enables sweeping the temperature between 1.8
and 300 K.
LTSYS-He3:
Operating down to 300 mK, this
state of the art system features integrated
designs for the He3 insert with the high efficiency
He bath cryostat. Reduction of the vapor
pressure is achieved by an internal sorption
pump (charcoal cooling) optimized for lowest
vibrations.
LTSYS-DIL:
Operating down to 20 mK, this
state of the art system features lowest base
temperatures for combination with e.g. the
confocal microscopy insert attoCFM II.
