eMorpho-HP - Selection Guide

There are 3 sets of options for the eMorpho high performance MCAs.

Select the speed and accuracy of the waveform digitizing ADC:

10-bit @ 60 MSPS:

Most popular choice. Offers lowest power consumption and is ideal for use with NaI(Tl) and slower scintillators.

10-bit @ 100 MSPS:

Use with scintillators that are much faster than NaI(Tl), especially when very high count rates are anticipated (>0.5 Mcps). Recommended for use with LaCl₃ and LaBr₃

12-bit @ 20 MSPS:

Use for slow scintillators requiring light pulse integration times of 5 μs and longer, such as CsI(Na), CsI(Tl), CdWO₄

12-bit @ 80 MSPS:

Use with fast scintillators (NaI) when a high dynamic range is expected, for instance in prompt and delayed neutron activation analysis.

Select the power source:

USB-powered:

Most popular choice. Use when operating one eMorpho at a time. USB supply current is 240 mA to 310 mA.

Powered from 3.3 V

Use when operating multiple eMorphos on one computer. Lowers overall power consumption. USB supply current per device is only 25 mA.

Select the PC-board shape:

2-inch Ø round

Smallest footprint. Use when embedding within a 2-inch detector housing. Board has headers for USB and JTAG connectors.

2-inch square

Convenient to use. Board has common-sized connectors, such as a USB mini-B connector and a Molex 2x7, 2mm pitch header that mates with a Xilinx JTAG platform cable.
