SINGLE AND DUAL-POINTING DEVICE FOR MOVING THE SAMPLE LU-40 KIPT

Abstract

Developed two electro-mechanical device with remote control, designed to move the samples one and two dimensions in a highbackground radiation. Samples movement carried in mechanical block by stepper motor with holding torque 5.6 kgf·cm and angle precision 1.8°/step. Motor control and control of samples coordinates implements by dint on electronic block, based on PIC16f76 microcontroller and Usart-RS485 interface converter based on Max 485 microchip. Devices can move objects weighing up to 100 g with an accuracy of 0.5 mm. The testing of the two-coordinate device in experiments on electron beam accelerator LU-40 KIPT have been held. The two-dimensional distribution of relative density of the flow distribution of brake γ-rays have been measured by ionization detector.
