The observations at millimeter wavelength begin to occupy an important role in the modern astronomy. The fast growing up of millimeter--wave bolometer array systems, such as SCUBA on the JCMT, MPfIR on the IRAM telescope or SuZIE on the CSO, have opened a new window that have allowed astronomers to make significant contributions in such diverse fields as the study of primeval galaxies and the early universe, anisotropies in the CMB due to the Sunyaev-Zel'dovich effect and protostars located inside dense molecular clouds. Bolocam is a new millimeter--wave camera with 144 pixels. It will operate at wave lengths centered at 1.1, 1.4 and 2.1 mm with a spatial resolution of 43'' ($\lambda = $1.4~mm) at CSO telescope and 8'' at the LMT/GMT. This camera will have a mapping speed two orders of magnitude larger than any of the previous mentioned cameras. The sensitivity of Bolocam is determined by the cryogenic system. This poster describes the actual stage of the cryogenic system which will cool the Bolocam receivers down to 300mK.
