The generation of an isolated attosecond gamma-ray pulse utilizing Compton backscattering of a relativistic electron bunch has been investigated. The energy of the electron bunch is modulated while the electron bunch interacts with a co-propagating few-cycle CEP (carrier envelope phase)-locked laser in a single-period wiggler. The energy-modulated electron bunch interacts with a counter-propaga...

The operation of a high energy particle accelerator facility is accompanied by neutron fields which are widely distributed in energy. As the neutron component dominates the dose outside the shielding neutron dose meters are needed for monitoring the radiation level at beam lines and experimental areas which can be accessed by personnel. For this purpose the so-called neutron rem-counter of the ...

In this experiment we observe the distribution of radiation emitted by a Cs source. Using a scintillation counter, we count the number of gamma rays emitted by the radiation source at four different mean count rates: 1 sec−1, 4 sec−1, 10 sec−1, and 100 sec−1. From this we can plot the distribution of counts/sec versus the frequency of count rate. We find the distributions for the different mean...
