Description
Cosmic Microwave Background experiments need to measure instrumental systematics very accurately to achieve their scientific goals. As a result of that, it is necessary to properly characterize these telescopes. However, natural sources cannot be used to calibrate all the properties of the instrument but we need to complement these with artificial sources. For this reason, we developed the PROTOtype CALibrator for Cosmology, PROTOCALC, which is a calibrator source designed for the 90 GHz band of these telescopes. This source is purely polarized and the direction of the polarization vector is known with an accuracy better than 0.1°. This source can be used to study optical properties such as beam size and polarization angle.
