Cryogenic technology for tracking detectors
Granata, V., Da Via, C., Watts, S., Borer, K., Janos, S., Pretzl, K., ...
A low-mass cryogenic cooling technique for silicon sensor modules has been developed in the framework of the RD39 Collaboration at CERN. A prototype low-mass beam tracker cryostat has been designed,...
Irradiated silicon detectors operated at cryogenic temperatures: the Lazarus effect
Granata, V., Bell, W.H., Berglund, P., De Boer, W., Borchi, E., Borer, K., ...
An increasing interest in the behaviour of silicon detectors at cryogenic temperatures has been awakened by the discovery of the so-called Lazarus effect, namely the recovery of charge collection...
Radiation hardness of cryogenic silicon detectors
Niinikoski, T.O., Abreu, M., Bell, W., Berglund, P., De Boer, W., Borchi, E., ...
We shall review test results which show that silicon detectors can withstand at 130 K temperature a fluence of 2 x 10(15)cm(- 2) of 1 MeV neutrons, which is about 10 times higher than the fluence...
Radiation hard position-sensitive cryogenic silicon detectors: the Lazarus effect
Palmieri, V.G., Abreu, M.C., Bell, W.H., Berglund, P., De Boer, W., Borchi, E., ...
The discovery of the so-called Lazarus effect, namely the recovery of the charge collection efficiency (CCE) of irradiated silicon detectors by means of cryogenic cooling has entailed an increasing...
Silicon detectors irradiated "in situ" at cryogenic temperatures
Ruggiero, G., Abreu, M., Bell, W., Berglund, P., De Boer, W., Borer, K., ...
Though several studies have proved the radiation tolerance of silicon detectors at cryogenic temperatures, following room temperature irradiation, no previous investigation has studied the behaviour...
Verbitskaya, E., Abreu, M., Bartsch, V., Bell, W., Berglund, P., Bol, J., ...
We present a study of the modeling of the electric field distribution, which is controlled by injection and trapping of nonequilibrium carriers, in Si detectors irradiated by high neutron fluences....
Zhou, X, Berglund, P, Zhao, H, Liljeström, P, Jondal, M
The Semliki Forest virus (SFV) expression system can be used to package recombinant RNA into infectious suicide particles. Such RNA encodes only the SFV replicase and the heterologous protein but no...
