We report a cryogenic detector with a superconducting phase transition thermometer and SQUID read-out for time of flight (TOF) mass spectrometry of biomolecules. Cryogenic detectors combine 100% detection efficiency independent of the mass of the molecule, an excellent energy resolution and a low threshold. Implementation of the cryogenic detectors into TOF mass spectrometers is expected to improve the efficiency of the detection of large biomolecules. To reach a high time resolution, we have developed two new read-outs based on a double stage SQUID and a cooled amplifier.
