2.5 MeV Neutrons
For a 2.5 MeV neutron generator:
a) 1D2 + 1D2 -->2He3 (0.82 MeV) + 0n1 (2.45 MeV)
b) 1D2 + 1D2 -->1T3 (1.01 MeV)+ 1p1(3.02 MeV)
Reactions a) and b) occur with equal probability.
Budget DD model
- 2x107 DD n/s maximum with 230 VAC mains power (1.2x107 DD n/s maximum with 120 VAC)
- Continuous output
- Very fast start to maximum performance. No run-up.
- The Central Controller and HV DC Power Supplies is in a 19" rack housing
- Air cooled to transfer the 1.8 kW maximum thermal emission.
- Chamber operational lifetime between DD gas refill servicing will be at least 25,000 hours but probably 50,000 hours but without the half life decay characteristic of 252Cf nor the short lifetimes of the old beam-solid target technology.
- The total life cycle cost economics of our products compared to other neutron source technologies is more attractive.
- All models include the specification of long lifetime of at least 25,000 hours of operation.
Industrial DD Model
- ~ 1x108 n/s with an electrode of at least 250mm
- Longer line source neutron emission zones are feasible
- Continuous DC
- Pulsed Neutron emission mode up to 10 kHz --user commanded
- Pulse duration of 2-20 micro µ second pulse duration -- user commanded
- Maximum duty cycle on time 2%
- Fixed Voltage
- Variable current per pulse -- user commanded
- High stability and repeatability
- All models include the specification of long lifetime of at least 25,000 hours of operation.

High End DD Model
An example of a high end neutron generator system:
- 1.25x109 n/s pulsed
- Electrode minimum length 300mm for 12kW
For more neutron flux, consider a multi-head configuration.
