Abstract

The invention of a new type of highly sensitive HTS/Hall-magnetometer which can be produced in large quantities with excellent reproducibility and operated with relatively simple non-feedback electronics offers the possibility for the development of unexpensive commercial systems for nondestructive evaluation. In order to meet the market requirements a cryogenic sub-system based on an AIM SL200 split Stirling cryocooler is currently under development at ILK Dresden (Institut fur Luft- und Kaltetechnik Dresden). In this contribution we will discuss the particular advantages of the new magnetometer concerning cryocooler operation. The design of the cryogenic test unit will be presented
