Outline
Experiment Construction of the system Information about communication Benefits of the project
Experiment NERA spectrometer is used to study
inelastic scatering of electrons. Three kind of measurements: QENS
(quasi elastic neutron scatering), IINS (inelastic incoherent neutron scatering) and ND (neutron diffraction)
16 meausuring segments (each segment contains 2 stepper motors and 2 monocrystals)
Bragg Reflection used to selected neutron energy
Construction of the system
Pin with monocrystal
Angular position indicator
Gearbox Stepper motor
Information about communication
Controler of stepper motor: OSM-17RA-BL
Data transmisionstandard: RS-485
Communicationsprotocol:MODBUS RTU
About software
Programming environment: Borland C++ Builder 6
Additional library: ComPort 3.0
Window of created software
Benefits of the project
Acceleration engine calibration Control via Gui People are not exposed to radiation
