DP5 Family

Amptek has a family of products built around its core DP5 digital pulse processing technology, designed

for pulse height spectroscopy. It was originally designed for the detection of ionizing radiation, principally X-

ray and gamma-ray spectroscopy. A generic system, illustrated below, includes (a) a sensor, a.k.a. detector,

(b) a charge sensitive preamplifier, (c) analog prefilter circuitry, (d) an ADC, (e) an FPGA which implements

pulse shaping and multichannel analysis, (f) a communications interface, (g) power supplies, (h) data

acquisition and control software, and (i) analysis software.

Digital Processor (DPP)

The core DP5 technology shared by all the systems includes the ADC, the FPGA, the communication

interface, and the data acquisition and control software. All products in the DP5 product family include nearly

the same digital signal processing algorithms, the same communication interfaces (both the primary serial

interfaces and the auxiliary I/O), and use the same data acquisition and control software. The DPPMCA

software package is a complete data acquisition and control application used across the family; Amptek also

offers an SDK for custom software solutions.

The products in the DP5 family differ in the sensor for which they are designed, which leads to changes

in the analog prefilter, power supplies, and form factor. They also differ in their completeness: some of

Amptek's products are "complete", with elements (a) through (i), while others offer only a portion of the

functionality for the user to integrate into a complete system.

X-123 Options and Variations

Detector

The X-123 is available with any of Amptek's standard detectors: FastSDD, SDD, SiPIN, and CdTe. Each of

these is recommended for a different application and the X-123 hardware will only accommodate one

detector type.

o The X-123-FastSDD is Amptek's highest performance detector, providing both the highest resolution

(as low as 125 eV FWHM at

low energy window, for measuring low energy X-rays, down to the Be K

recommended for count rates > 100 kcps and, with the C2 window, for measurements < 1 keV.
