Fissile materials (235U, 241Am, Plutonium…) emit neutrons. Those neutrons are captured in their surrounding and emit prompt gamma rays that Temporal Compton camera detect well. It is imposible to detect directly the weak lines of 235U (185 keV) or Plutonium which are below 300 keV with a compton camera. Anyway those lines are difficult to correctly image with coded mask cameras in realistic situations because they are screened […]
Our camera can be used in the standard mode till 1mSV/h. At those high count rate, the acquisition time should be short although: you can get 22.000 events in 10 seconds! We have also identified a mode allowing to use our camera at 6msV/h or even 10 mSV/h. This requires a specific hardware and must be specified in your order. On the image below you […]
Thank you Bpifrance for this opportunity to share DAMAVAN IMAGING ideas and solutions!
Container with a roughly 1 MBq 60Co source seen from 3m (30’ image)
The unique gamma image of 2 60Co sources obtained by Temporal V3: 2 60Co sources in the lab with a large intensity contrast (1 to 8) are clearly separated with an angular separation of 10° ;Activity of the main source 300 kBq ;Distance to main source = 0,8m ;Acquisition duration 1h (in order to get > 500 photons from the weakest source) ;Threshold = 14% […]

Damavan Imaging attended the 7th East Asia Forum on Radwaste Management organised by the Korean Radioactive Waste Society (KRS) from 26 to 28 October 2022 in Jeju Shinhwa World Landing Convention Center, South Korea. That was a great chance to exchange with our welcoming partner RMTEC and other participants on the latest industry issues and to test our products. Damavan Imaging could demonstrate resolved image of 137Cs […]
Damavan will present an oral and poster presentation at the 2022 IEEE Nuclear Science Symposium, Medical Imaging Conferance and Room Temperature Semiconductor Detector Conference. The conferance will take place at the Milano Convention Centre, Milano, Italy, from November 5th to November 12th. The poster title is: »3D Compton tomography: A promising modality for vectorized α/β radiotherapy imaging?« . The poster will be presented in the M-04, MIC […]
With our Compton Camera, thanks to it’s high spatial resolution and good signal/noise ratio, it is possible to image heavily shielded sources. In this case we are observing a high activity (1GBq) ¹³⁷Cs source used for level gauging. The source is shielded by 20 cm of lead. In 10 minutes using the 80 photons on a total 20.000 selected on the ¹³⁷Cs peak (662 +/- […]
