We tested the influence of microwave field on a cosmic ray detector which consist of a photomultiplier tube (PMT) type EMI 9656B and a NaI(Tl) crystal scintillator. We investigated the PMT output signal when the PMT is optically coupled with NaI(Tl) crystal scintillator and when the PMT is separate of NaI(Tl) crystal scintillator. We found that the PMT generates output signal to PMT anode when is exposed to a microwave field. When the PMT is optically coupled with NaI(Tl) crystal scintillator the PMT anode amplitude increases. As microwave source we used a commercial magnetron, which emits 2.45 GHz frequency with 800W microwave power and a cylindrical waveguide having TM011 propagation mode..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
