A crystalline, silicon, microelectronic, cryogenic, thermal detector for single quanta of low energy radiation and high resolution spectroscopy is being developed. Its volume is less than 0.1 mm3. The constituent parts of the detector are integrated in one unit by micromachining. The dependence of the resistance of the thermistor on temperature (R-T characteristics) has been studied experimentally. The influence of changes in the implantation dose of the thermistor on the R-T characteristics has also been studied. To obtain the best energy resolution of the detector the optimal implantation dose of the thermistor has been determined. The amplified detector pulses were fed into a Macintosh computer via an especially developed computer interface. The operation of the detector was tested by sampling gamma, X-ray and electron spectra from a 109Cd source.

      Abstract Fabrication of a thermal detector designed for high resolution spectroscopy of low-energy radiation is described. Details of the micromachining of pure silicon are given including the etching of the 0.1 mm3 absorber and the doping process to obtain the temperature sensing thermistor which is an integrated part of the absorber. The cryogenic system, the signal processing at working temperatures around 50 mK and the data acquisition system are discussed. Theoretical aspects of the intrinsic resolving power are presented. The relation between the intrinsic detector resolution and particle energy at different working temperatures is derived. Measured resistance vs temperature is shown for thermistors made with different doping on wafers with different initial wafer resistivity. The influence of the initial wafer purity on the R-T characteristic curves is discussed. The optimal implantation dose was determined for thermistors implanted in high purity wafers. Download

      Abstract We suggest a new type of temperature sensor in low temperature composite bolometers for detection of nuclear radiation. The new sensor is a two-dimensional (2D) array of ultrasmall (∼0.01μm2) aluminum Josephson junctions, situated on a micro machined silicon absorber. The incident radiation creates phonons in the absorber, which in turn can excite either charge solitons or vortex solitons in the 2D array. The benefit of this sensor is the low operation temperature, which is determined by the activation energy for the solitons, and can easily be as low as 20 mK. A low operation temperature is essential since the specific heat of the absorber has a T3 dependence. The activation energy can be set to the desired value by changing the individual junction sizes as well as the junction resistances. Furthermore, the optimal operation point may be trimmed by a moderate magnetic field. Since the atomic mass of aluminum is very close to that of silicon the Kapitza resistance between the absorber and the sensor is small. By keeping the aluminum electrodes in the superconducting state, the amount of additional electronic heat capacity from the sensor may also be kept low. Download

      Silicon Drift Detectors for Synchrotron Energy Dispersive X-Ray Fluorescence Spectroscopy (SDD for EDXRF) Presentation by Dr. Saleh Qutaishat Petra University A Silicon Drift Detector (SDD) is presented. The detector structure and its working principle are explained. The detector is cooled by a Peltier cooling element giving it a great advantage over other types of liquid Nitrogen cooled detectors. The detection system has a high energy resolution due to the low output capacitance of the SDD detector and the integration of the FET transistor on the detector. Energy resolution of the system is 125 eV FWHM at 5.9 KeV Mn K. Due to its short time shaping signal SDD has a high count rate of 500,000 counts per second. SDD detectors are famous in being used in Synchrotron energy dispersive x-ray fluorescence (EDXRF) spectroscopy and in portable XRF analysis devices. Download

      Abstract Silicon Lithium Detectors for Synchrotron Energy Dispersive X-Ray Fluorescence Spectroscopy (SiLi for EDXRF) by: Dr. Saleh Qutaishat. A Silicon Lithium Si(Li) detector is presented. The detector structure and its working principle are explained. The detector is cooled to 77o K by liquid Nitrogen. The detection system has a high energy resolution. Energy resolutions of the system at active areas of 10, 30, 50, 80 (mm2) of the detector are 127, 133, 139, 148 eV FWHM at 5.9 KeV Mn Ka. Si(Li) detector has efficiency greater than 25% over a range of x-ray energy of (1.5 KeV – 25 KeV) and it can be used for energies greater than 25 KeV. Si(Li) detectors are famous in being widely used in Synchrotron Energy Dispersive X-Ray Fluorescence (EDXRF) spectroscopy. Efficiency of Si(Li) detector is compared with efficiency of the superior Silicon Drift Detector SDD by having a higher count rate. Also, its efficiency is compared with the efficiency of Cadmium Telluride CdTe detector that covers energy range of (40 KeV – 100 KeV). Download

      Abstract The development of integrated silicon microcalorimeters with high resolving power for low-energetic single quanta of radiation is being carried out. The optimum thermistor implantation dose has been found, and measurements have shown, that our detectors are very sensitive. The experimental set-up, however, suffers from mechanical vibrations, which are picked up by the cryostat and amplified in there. Measurements of the frequency spectrum of the noise gave evidence for this interpretation. All necessary steps to improve the damping are being done. Furthermore, the development of a cryogenic preamplifier has been started, meant to reduce electronic noise. The influence of wafer purity which was observed earlier, could be determined and verified by measuring the implantation profiles by the secondary ion mass spectrometry method. Beside that, studies of hopping conduction phenomena, the processes responsible for the observed temperature dependence of resistivity, have been performed. It could be concluded that the model of Coulomb gap variable range hopping is supported by our experimental data over a wide temperature range. Recently, the study of magnetoresistance effects was started. Download
