Description
Summary
A new type of radiation monitors is presented that does not need any external cabling. Using special selected Li batteries, integrated levels of the total dose, 1 MeV n and h > 20 MeV are continiously stored for a period of maximum 680 days. The data is stored in triplicated, sepreately powered registers for a maximum of 10 years and can be read out at any time. The key points in the design were to lower the current consumption of the entire device to 1.6 mA, to make it radiation resistant up to 200 Gy and to make it operate reliable in the magnetic fields of CMS/ATLAS. To retrieve the data from a device, a USB interface in combination with a Labview application is used that can be installed on mini-PCs and on handhold computers. The readout operation takes only a few seconds which means a considerable improvement with respect to classical passive dosimeters.
