he radiation shielding capabilities of polymers and Martian regolith simulant MGS-1 are analysed by means of the dose reduction of the absorbed dose radiation quantity. MGS-1 is an analog for Martian surface material while polymers are generally an effective radiation shielding m ...
Commissioning studies of the CMS hadron calorimeter have identified sporadic uncharacteristic noise and a small number of malfunctioning calorimeter channels. Algorithms have been developed to identify and address these problems in the data. The methods have been tested on cosmic ...
The CMS Hadron Calorimeter in the barrel, endcap and forward regions is fully commissioned. Cosmic ray data were taken with and without magnetic field at the surface hall and after installation in the experimental hall, hundred meters underground. Various measurements were also p ...
