Chandrayaan-1 Energetic Neutral Analyzer (CENA) sensor of the SARA ex-
periment is a neutral particle detector which detects neural atoms in 
the energy range 10 eV- 3.3 keV with an energy resolution of 50% and  
thereby enables to find the mass of neutral atoms sputtered from luna-
r surface. CENA consists of 4 subsystems, which are a Charged particl-
e removal system, a conversion surface, an energy analysis system and-
a system to provide the time of flight analysis. It is capable of res-
olving all major mass groups H, O, Na-Mg group, K-Ca group and Fe. Da-
ta from CENA is sent to the DPU (Digital Processing Unit) which does  
the processing of time-integration, binning and packetise the data and
send to the telemetry.The basic measurement cycle for CENA is 4s.
