The essential features of this equipment are: Each of the two HV Power supply shall provide very stable, continuous adjustable, well regulated HV with low noise in an output range from 0 to 5000 V and from 0 to 500 V. Each outputs shall be able to deliver positive and negative HV polarity (selection of the polarity by mechanical switch). The output current shall go up to 100 µa. Voltage shall be available at SHV connectors for 5kV and 500V output, for each of the two power supply element. Noise on the output shall be less than 10 mv (peak to peak, at 5 Hz to 50 MHz). Input power shall be taken direct from the NIM bin power supply (±12 and ±24 V DC). For each element a digital display or a segment bar graph shall allow to monitor the output Voltage. LEDs shall indicate the selected output polarity before the HV ON/OFF switch is turned on. A remote shutdown feature shall protect germanium or silicon detectors when warming up. For this purpose a shutdown input, to receive the signal from the preamplifier, a LED to indicate the shutdown and a reset button to manually cancel the shutdown mode shall be implemented in each element of the NIM module. The shutdown feature shall be compatible to TTL logic level output signals of certain detectors. In case any of the detectors demands excessive output current, the HV outputs shall be automatically protected against overload. The overload shall be indicated by a light. After overload the module shall recover automatically. The adjustment of the output voltage shall happen at the front panel via precision potentiometer(s). Timing Single Channel Analyser TSCA This NIM module shall performs single channel pulse high analysis and timing signal derivation. The essential features of this equipment are: The TSCA shall process bipolar and unipolar signals and shall operate in three different modes: Integral (UL is disabled and LL sets a single discriminator threshold between 0 and 10 V), Normal (LL and UL as independent adjustable levels within 0 to 10 V) and Window (LL as baseline level between 0 and 10V, UL sets window width (1-10V)) mode. To select the modes a mechanical switch at the front panel shall be installed. 30 P age

31 The selection of the Low level (LL) shall be done via turn potentiometer for continuous adjustment from 0 till +10 V. The manipulation of the Upper level (UL) shall be done via turn potentiometer for continuous adjustment from 0 till +10 V in normal mode, or 0 till +1 V in windows mode. The selection of the time delay shall happen via turn potentiometer for continuous adjustment of the output delay range between 0.1 up to 11 µs. To compensate the walk an adjustment screw at the front panel shall be available The DC input, a SCA output with positive polarity and a SCA output with negative polarity shall be available as BNC connectors at the front and rear side. Additionally, the module shall have LL and UL NIM output standards. The dynamic rang shall be minimum 200:1 Multi Channel Analyser NIM module: Dual-input Multichannel Analyser System with interface connection option to a computer. The essential features of this equipment are: Each of both inputs shall process the signal via a fast 16k ADC and store data in sufficient on-board memory. The conversion time shall be less than 1.5 µs, and the resolution shall be adjustable for 16k, 8k, 4k, 2k, 1k, or 512 channel applications. The module shall have dead time correction methods, including Gedcke-Hale and ZDT method. The input shall accept positive unipolar gated integrator, or positive leading bipolar analog pulses, and shall operate in the PUR (Pile up rejection), BUSY and ADC GATE input modes. The module shall communicate with a MCA emulator software, installed on a computer. The connection to a computer shall be established via a standard USB-2.0 interface. The emulator software shall be supplied with the MCA and shall have the following essential features: Fully operational at Windows XP and W7 32 bit systems. True live data display GUI easy to operate Real time/live time selection Create Region of Interests with information on centroid, peak count, integral count Data stored on the computer shall have a standard universal readable (e.g.: by text editor) format, proprietor files (just readable by own software) are not allowed. Counter/Timer/Rate Meter NIM Bin module for counting pulses and displaying the actual values and cps rate by a count rate meter (CRM). The essential features of this equipment are: The module shall be able to process count rates up to 200 MHz. It shall consists of 4 counters and 2 timers. It shall have a pulse capacity of 32 bit and a pulse pair resolution of 7 ns or better. The module shall have minimum four front panel counter inputs, which accepts analog and digital pulses up to ±5 V in amplitude. Furthermore it shall have up to six front panel inputs, which accept TTL signals, and minimum two outputs which act as TLL output. All signal inputs and outputs shall be BNC connectors. Each counter or timer shall have a 128 word First in first out buffer. Counting thresholds shall be computer adjustable. 31 P age

32 A standard USB-2.0 plug shall be available at the rear panel to connect the module with a computer to transfer and display the collected information to a Counter/Timer/Rate Meter Software. Software shall also be responsible to adjust and store setup parameters. The Counter/Timer/Rate Meter software shall be supplied with the counter/timer module and shall have the following essential features: Fully operational at Windows XP and W7 32 bit systems. Easy to operate GUI for all input signals Each counter shall display the actual digital counter value, an analogue CRM (graph in the design of a tachometer with selectable logarithmic or linear units, a CRM showing counts per second (cps) rates, input selection, threshold alarm light and a reset button Setup of parameters for each counter (signal threshold, polarity, alarm threshold and impedance) Oscilloscope The compact digital oscilloscope shall have the following essential features: Minimum bandwidths of 100 MHz Two channels Sample Rate 1.0 GS/s Real Time, or better 34 Automatic Measurements Advanced triggers including pulse width trigger and line-selectable video trigger Colour LCD Display (optional: additional monochrome mode), minimum 7 with minimum resolution of 800x480 pixel.
