The objective of the project is to design, develop and test four prototypes of Miniaturised Radiation Monitor (MIRAM) which
Main technical requirements for MIRAM
The radiation monitor MIRAM is based on one of the best available technology for particle detection - Timepix. It allows for significant reduction of the size of the device as the dimension of the Timepix chip has size of just 14mm x 14mm and weighs only a fraction of a gram. At the same time, it offers an unprecedented performance of particle detection, tracking and recognition, as it consists of 256 x 256 silicon pixels of which each operates as an individual particle detector by its own.
The architecture of the device is based on a hybrid active pixel detector technology with diodes and shielding. The heart of the design is the Timepix chip with the read-out electronics. The particle species identification is designed with the sophisticated combination of the pulse height analysis, the coincidence scheme with absorbers and the analysis of cluster shapes and energy depositions.
The project is planned to take a total of 32 months. The outcome of the first year is a full design of the MIRAM device supported by simulations and tests of main components. The outcome of the second year is a production of four prototypes of MIRAM. The rest of the project period is dedicated to the prototype validation and irradiation testing, and to creating a MIRAM flight units development plan proposal.
The project has started as of 1st of January 2018. After the first progress meeting, the initial activities are carried on. Mainly the technology selection is finalized and the feasibility and risks are duly analysed. The simulations of the MIRAM performance has started.
