|---|---|
| Temperature range | 2.2 K with helium, or 56 K with nitrogen, up to 330 K |
| Temperature stability | equal to or better than 0.3 K |
| Temperature gradient | equal to or smaller than 0.3 K |
| Specification | Liquid nitrogen volume 8.4 l, liquid helium volume 5.1 l |
| Liquid helium stand time | 24 h unheated at liquid helium temperature |
| Absorption of gamma radiation by the mylar windows | less than 1 per cent |

A liquid nitrogen top loading bath cryostat for Mossbauer spectroscopy with the source at ambient temperature. The stainless steel body and low consumption give long stand times, and samples can be exchanged in cold condition.
A compact single width NIM high voltage supply for radiation detectors, available in 3 kV and 6 kV versions. It is short circuit and overload protected, and warns by flashing LED and tone if the overvoltage limit or the NIM bin supply fails.
A temperature controller for the WissEl Mossbauer bath cryostats. It reads a DT-670 silicon diode inside the cryostat through a four wire connection and drives the cryostat heater from a built-in Eurotherm 3216 control module.
