MBBC-HE0106 | MBBC-HE0106 MÖSSBAUER He / N2 CRYOSTAT | | The Bath Cryostat MBBC-HE0106 is designed for low-temperature Mössbauer spectroscopy with the Mössbauer source at ambient temperature. The cryostat is entirely made of stainless steel. A silicon diode DT-670 inside the cryostat is used as temperature sensor for the temperature controller TR-50. FEATURES - Liquid helium and liquid nitrogen operation
- Temperature range from 2.2 K (He) or 56 K (N2) by pumping down up to 330 K
- Temperature gradients less than 0.3 K (sample in He or N2 atmosphere)
- Long stand times due to low cooling liquid consumption (e.g. He ~ 0.164 l/h)
- Top-loading Mössbauer cryostat
- Easy sample change in cold condition
- Sample holder with a cylindrical hole of Ø = 20 mm for sample insert
In addition to the standard cryostat MBBC-HE0106 further cryostats with stand times for helium operation up to approx. 39 hours are available (see section special versions further below). | SPECIFICATIONS | Technical Characteristics (standard version) | Temperature range | He: 2.2 K (by pumping off He gas) - 330 K N2: 56 K (by pumping off N2 gas) - 330 K | | | Temperature stability | equal or better than 0.3 K | | | Temperature gradient | equal or smaller than 0.3 K | | | LN2 Volume | 8.4 l | | | LHe Volume | 5.1 l | | | LN2 stand time | 7 days when filling helium bath and nitrogen bath with nitrogen | | | LHe stand time | 24 h (in unheated condition at LHe temperature) – see special versions further below) | | | Absorption of γ-radiation by Windows | < 1 % | | | | Materials | Cryostat body | Stainless steel | | | Windows | Mylar | | | Sample holder | Copper | | | | Physical | Diameter of Mössbauer absorber | 20 mm | | | Distance between outer windows | 40 mm | | | Length of cryostat | 900 mm | | | Diameter of cryostat | 255 mm | | | Weight | 30 kg | | | | Special Versions | LHe stand time (approx.) | Length of cryostat (about) | LHe volume |
