ALMA hosts guided visits for groups from schools, universities, institutes and related scientific organizations. The visits include a tour of the Operations Support Facility (OSF), the camp where ALMA personnel work and where visitors can observe antenna maintenance, the control room, laboratories, and usually an antenna transporter. For safety reasons, operations on the Chajnantor Plateau (the Array Operations Site, or AOS, where the antennas are located) are not open to visitors, due to the location at 5,000 meters above sea level.
All visits must be coordinated at least one month in advance by providing all of the information required on the form below. Once a group receives authorization, the contact for the group will receive a confirmation email.
The visiting group must have its own means of transportation to the Observatory (OSF or the ALMA camp).
