ALPACA, the Advanced L-band Phased Array Camera for Astronomy, is a phased-array receiver capable of providing high sensitivity observations simultaneously for 40 beams on the GBT in the 1-2 GHz band.
ALPACA is one of the most advanced phased array feeds for wide-field imaging developed to date. It is the first such instrument to include a large number of array elements within a cryogenic dewar so that both the front end electronics and antenna elements are cooled. Installed as a receiver on the Green Bank Telescope, ALPACA will enable unprecedented survey capability for pulsar and radio burst detection, through probing the diffuse intergalactic gas leftover from the cosmic dawn, and mapping radio recombination lines, solar radio bursts, and the magnetic fields of the diffuse interstellar medium.
With the intention of maximizing the science return from this instrument, and advertising it to a diverse group of astronomers as possible, GBO invites members of the scientific community for a four-day workshop on April 25-28, 2025. In addition to outlining key science projects for ALPACA, it is intended that the workshop will allow potential users to learn about the instrument, form collaborations, and aid in the planning and commissioning of the instrument
The Workshop will be held at the Green Bank Observatory, where the great natural beauty and intimate setting produce meetings characterized by a high level of interaction. Because of logistical considerations, attendance will be limited to 45 participants.
Pre-Registration
Pre-registration for the meeting is now open at: https://forms.gle/kc9NSYcjERjddzKq5
Lodging
Lodging will be at the Observatory or nearby locations and all meals will be served in the Observatory Cafeteria. All lodging and meal costs will be covered for participants.
Travel Information
The easiest way to get here is to follow the directions on our “Getting Here” page. Please note that some GPS systems do not always give the best route to the Green Bank Observatory, and nothing beats the good old-fashioned paper map for navigation.
We will attempt to coordinate ride-sharing from airports if there is interest.
