Abstract
CubeSats are playing a vital role in the development of new compact technologies for small satellites and because of their promising potential, the CubeSats have been widely embraced by universities for conducting space research projects. IITMSAT is a student driven Nano-satellite embraced by IIT Madras leading to the development of Space-based Proton-Electron Energy Detector (SPEED). It is a payload that is being developed to be launched on-board IITMSAT. The scientific objective of the payload is to gather data on the variations in the charge particle flux below the inner Van Allen radiation belts. SPEED is designed to obtain energy spectra of high-energy protons and electrons, specifically designed to investigate correlations between variations in these spectra and seismic activity, solar flares and lightning storms. The SPEED electronics consists of Peak hold Detector, Charge-Sensitive Pre-Amplifier, TIVVA microcontroller and Photo Multiplier Tubes. This paper describes the development of the high voltage power supply for the photo multiplier tubes (PMT) of SPEED. In SPEED, photo multiplier tubes operates at around 1000 V to 1300 V with very strict ripple requirements and requires very precise and controlled high voltage. Due to their high gain and extremely light sensitivity photomultipliers (PMTs) can easily be damaged by applying excessive light to the photocathode and thus exceeding the maximum output current. A novel compact and controllable high voltage power supply based on integrated DC-DC converters is developed which provides ultralow ripple of about 0.3% to 0.5% at an output of 1000 volts which is further reduced by the 5th order low-pass filter circuitry. Innovative automatic current protection circuitry is developed for protecting PMT from being damaged by saturation current. We are able to develop voltage monitoring and regulation system for high voltage with a voltage regulation of 0.1%. Voltage regulation is achieved by control software based on TIVA microcontroller based solution. A number of tests have been performed to provide very reliable and efficient high voltage power supply for PMT. This poster reflects upon the development of ultra-low noise and ripple power supply for the photo multiplier tube. The goal is to creat a very reliable high voltage power supply for the photo multiplier tubes of SPEED and this poster reflects upon the development of same.
