Technical design and performance of the NEMO3 detector

The development of the NEMO3 detector, which is now running in the Frejus Underground Laboratory (L.S.M. Laboratoire Souterrain de Modane), was begun more than ten years ago. The NEMO3 detector uses a tracking-calorimeter technique in order to investigate double beta decay processes for several isotopes. The technical description of the detector is followed by the presentation of its performance.Comment: Preprint submitted to Nucl. Instrum.

TELIS: A novel three-channel cryogenic heterodyne receiver for stratospheric research

TELIS (TErahertz and sub millimeter LImb Sounder) is a three-channel balloon-borne cryogenic heterodyne receiver on which a number of novel features are tested. It will fly together with the MIPAS-B2 instrument and the combination will yield the most complete map of atmospheric species ever measured from one platform. The three channels are selected at 500 GHz, tunable between 500 and 650 GHz and at 1.8 THz, and employ a SIS mixer, a Superconducting Integrated Receiver and a HEBM. First flight is foreseen in 2006
