Activities of IEAP in the ATLAS experiment

• Our fields of activities: SCT FWD – construction, testing ATLAS-MPX/TPX detector system

Radiation background measurement Luminosity measurement

Data analyzing From ATLAS-MPX/TPX “Complex” ATLAS data – taul leptons, ttH

(H→ττ) Study of physics, possibly observable in

the ATLAS experiment Effects of KK gluons, top quark

physics,…

• Institute of Experimental and Applied Physics (IEAP) is the research institute of the Czech Technical University in Prague.

• 26 physicists and 2 technicians from the IEAP are involved in the ATLAS experiment.

• 13 physicists are registered as ATLAS authors.

MPX03 - Close to HEC electronics

What we can offer• Know-how of pixel and strip detectors

Development of read-out electronics Tests of the electronics Tests of detection properties

• Clean rooms Used for SCT tests during the ATLAS construction

What we can offer• Manual wirebonding machine• Fast osciloscopes, all necessary equipments for digital as well as analog testing

(coincidence/anticoincidence, ADCs, fast scintillators,…).• Sources of radiation for detector testing

X-ray; Alpha, beta particles (source of electrons with controlled energy); Radionuclide neutron sources (thermal as well as fast neutrons).
