The gamma-ray telescope IBIS, on Board the INTEGRAL satellite, is
expected to satisfy the mission's imaging objectives, by using two
position sensitive detection planes, one with 16384 Cadmium
Telluride pixels (ISGRI) at lower energies and the other with 4096
Caesium Iodide pixels (PICsIT) for higher energy detection. Given to the high complexity of the system, a dedicated Experiment Check Out Equipment (ECOE), was developed, capable not only to acquire, archive and monitor, the instrument data, but also to perform a fast data analysis, in order to deeply understand the instrument behavior in real-time. The system was used to support the IBIS Test and Calibration campaign campaigns, from the Engineering to the Flight model, and it will be used again during the Commissioning Phase, after
launch. We describe here, the architecture of the ECOE system and the
quick-look analysis tools that, with an user friendly graphical
interface, allows the user to analyze, in an easy way, both the
IBIS housekeeping and scientific data.
The IBIS telescope is the high angular resolution Gamma-Ray imager on-board the ESA satellite INTEGRAL. The scientific goal of IBIS is to address, complemented by the high resolution spectrometer (SPI), astrophysical processes from celestial sources and diffuse regions in the X and Gamma-Ray domain. IBIS, with its Cadmium Telluride detector of 16.384 pixels and Caesium Iodide detector of 4.096 pixels, is an instrument with an high degree of complexity, whose status is continuously monitored by thousands of parameters (count rates, temperatures, voltages, instruments status, etc.), transmitted to ground by the periodic and non-periodic satellite telemetry housekeeping packets. In this paper we present the 'Ibis Parameters MONitor' (IPAMON), the real-time quick look software, part of the IBIS Experiment Check Out Equipment (ECOE), used during the on-ground functional and calibration campaign of the IBIS flight model carried out in LABEN (Milano) and ESTEC (ESA, Noordwijk). Due the high number of parameters, the software was designed to be flexible. In fact using the instrument data base as input for the internal structure configuration, the software is then insensitive to modifications that can occurs in the contents of the packet telemetry.
This capability allows IPAMON to be easily used for any other mission involving ESA packet structured telemetry.
