MEASUREMENT OF COSMIC RAY USING NUCLEON AND TUS

INTRODUCTION

I am a student of third course in the University of Venda in Limpopo province in Republic of South Africa.I was doing a practice in Dr L Tkatchev group, where I was studying measurement of NUCLEON and TUS for cosmic rays problems.

NUCLEONregion

TUSregion

In the nucleon region there is little experimental data because it should be measured using a satelite .

TUS needs a wide surface to detect UHECR particles,its very costly to construct surface detectors with enough area

Principle of measurement of cosmic ray using TUS

NUCLEON apparatus consists of- NUCLEON detector as a monoblock inside of pressure container,- Special telemetry system inside of separate container, - Antenna-fider system,- Mechanical support interface of the connection with base satellite

system.

Main NUCLEON parameters:-Total weight ~ 265 kg (for detector ~165 kg);- Power cunsumtion~150 W (for detectors ~ 120 W);- Telemetry ~270 MB/day;- Data taking period ≥5 years.
