Product Overview
Analog to Digital Converter, Nuclear Instrumentation Module (NIM), Canberra Model 8715, Gain to 8K
Condition
Used, in good shape on visual inspection, with light scuffs on the side covers. It was marked functional before storage. Powered on here and it lights up; full function testing not performed. The gain selector tops out at 8K. The unit pictured is representative of stock. Markings legible: ADC 8715 and CANBERRA on the front panel, MODEL 8713/8715 and CE on the rear panel, and a Canberra Industries label on the rear connector housing reading 800 Research Pky, Meriden, CT, Made in U.S.A.
Ready to ship from our Idaho warehouse the same or next business day. Selling online since 1999.
Product Overview
Canberra's 8715 is an analog-to-digital converter in the Nuclear Instrumentation Module (NIM) format, the stage that turns each shaped pulse from a spectroscopy amplifier into a channel number for a multichannel analyzer. The front panel sets conversion gain from 256 to 8K, a digital offset, lower and upper level discriminators, and the choice of pulse height or sampled voltage analysis. Live time correction and pileup rejection signals connect at the rear.
Key Features
- Concentric GAIN and RANGE selector: 256, 512, 1K, 2K, 4K, 8K
- OFFSET toggles marked 128, 256, 512, 1024, 2048 and 4096
- ZERO, LLD and ULD front panel trims
- PEAK DETECT section: AUTO / DELAYED, INSP test point, ADJ trim
- PHA / SVA mode toggle and COINC gate toggle
- ADC IN and gate BNC inputs, BUSY bar display 0 to 100%
- 800 ns fixed dead time conversion
- Dead time bar graph of 20 segments, each 5% dead time
- Rear: DATA ribbon header, LTC/PUR connector, DEAD TIME BNC, two additional BNC jacks, NIM power connector
Applications
- Digitizing pulses from a germanium or sodium iodide detector chain for gamma spectroscopy
- Replacing a converter in an existing Canberra NIM multichannel analyzer system
- Teaching pulse height analysis in a university nuclear physics lab
Frequently Asked Questions
How many channels can it convert to?
The gain selector on this unit runs from 256 up to 8K.
Does it fit a standard NIM bin?
Yes. It is a NIM plug-in with the standard rear power connector.
Is a data cable or manual included?
Not included.
What am I getting, and what am I taking on?
A clean 8715 that lights up on power and was marked functional before storage, without a full test here. The photos are the spec. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
The rear panel answers to 8713/8715 while the front panel settles the question at 8715. Put a detector upstream and an analyzer downstream and it knows its job.
