The intelligent Photomultiplier Tubes for OSIRIS Open
The dimensions of liquid scintillator neutrino detectors have grown over the years. Thus, the analog cable length required for the readout increases. In consequence, the signal loss increases as well. With the intelligent Photomultiplier T…

E-TEST: a compact low-frequency isolator for a large cryogenic mirror Open
To achieve the expected level of sensitivity of third-generation gravitational-wave (GW) observatories, more accurate and sensitive instruments than those of the second generation must be used to reduce all sources of noises. Amongst them,…

Study of Prompt Gamma emission in $^{12}C (p, p' \gamma) C^{12}$ nuclear reactions close to a Bragg Peak Open
Proton therapy is a high-quality radiation therapy which uses a proton beam to irradiate cancer tissue. The advantage of this type of treatment is a highly conformal dose deposition due to the presence of the Bragg peak. It is often requir…
