Abstract

Magnetic field (B-field) is the most controversial factor in molecular clouds for star formation, necessitating further observations. The Star Formation Group at the Chinese University of Hong Kong is currently engaged in the construction of ROGer, Asia's inaugural polarimetry. ROGer will be installed on the 12-meter Greenland Telescope (GLT) and will facilitate the observation of B-field morphology within molecular clouds by utilizing dust thermal emission at 345 GHz. ROGer's polarization module introduces the novel implementation of Martin-Puplett interferometer (MPI) optics, enabling real-time sky noise elimination on the same detector through destructive interference. Two 157-pixel silicon-based aluminum film Microwave Kinetic Inductance Detector (MKID) arrays will be employed to detect the orthogonal signal from the MPI optics. Here we will present the prototype of our novel MPI polarimetry and optics design.
