[PCG22-P02] The development of new solar observing modes of ALMA
To utilize most observing functions of ALMA for solar observing, the international development team of ALMA solar observations works on the development of new solar observing mode. However, the machine time for commissioning is decreasing because the development of most observing modes had been finished and ALMA project shifted normal operating state. To develop solar observing modes effectively in such situation, we prioritized the observing modes based on the demands from the solar community. The current priority is following; 1) Higher observing frequencies (Band7 and Band9) that show temperature minimum and might realize higher spatial resolution, 2) Full-Stokes polarimetry to obtain the signal of the magnetic fields in the chromosphere (Band3), and 3) High-cadence scans of a small field of view with a single-dish observation. We are considering other modes, for instance, the flexibility of observing frequencies, and sub-seconds cadence. In the paper, we summarize the candidates of new solar-observing modes, and report the status of the development.
