Welcome to Gianluigi Casse’s home page
Here you can find summarised part of the silicon detector activity in the Physics Department of the University of Liverpool. You can also look to my personal page, by clicking here
Silicon detector studies
This page summarises the work done in the silicon detector laboratory of the HEP Group (University of Liverpool - Department of Physics)

Experiments I am involved
Atlas, LHCb, RD50. Some of the work I have performed in the framework of these experiments can be found below.
 Radiation tolerance of silicon detectors
The silicon detectors will provide the main tracking capability for the future experiments in high-energy physics. In most of these experiments they will have to withstand a harsh radiation environment. The survival of the detectors to the severe radiation fluences they will receive is a challenge for the detector technology. We are involved in the development of the sensors for several of the major experiments that will take place in CERN-LHC (ATLAS, LHCb) and FERMILAB (CDF). In this page I have collected several results concerning the study of silicon detectors mainly on the subject of their radiation hardness.

SCT ATLAS sensors page: a systematic study of the radiation behaviours of the sensors for the ATLAS tracker has been carried out for a few years. The Liverpool University was heavily involved in this program. A number of results obtained within this program is collected in the following section: pre and post irradiation characterisation of SCT ATLAS sensors.


 Studies for CDF Tests for the commissioning of the Layer00 for the CDF experiment have been carried here. Results are reported in my CDF-L00 page.

Studies for LHCb VELO: Tests for the development and commissioning of the VELO micro-strip detectors: big challenge for the proximity to the interaction point (the highest radiation field for micro-strips in LHC) and the complicated double metal design. Some of the results are reported in my VELO page. Links to the Liverpool web page are here.


 I report here some results relevant to radiation hardness of silicon detectors for high energy physics applications obtained in the Liverpool silicon laboratory and some result obtained during my work for RD48 at CERN.  Click below to open the relative pages.
