On February 18, the NAOJ Advanced Technology Center shipped out the last seven ALMA Band 10 receivers to Chile. This marks the completion of delivery of a total 219 receivers for three frequency bands developed by NAOJ.

The development and production were complete in December 2013 (See "Completion of the ALMA Receiver Development" on Dec 27, 2013 on Latest News) After this, the receivers had preliminary in-house acceptance tests, packing, attachment of shock logger to record the shock given to the product during transport, and applicable export procedures. On the day of the last shipping, members of the Band 10 development team saw off the receivers contained in a shipping case and loaded on a truck, saying goodbye to them.

The picture shows Yasunori Fujii, a research engineer and a member of the Band 10 development team, during packing of a receiver in a metal transport container.

The receivers in a metal container were packed into a hard transport case with cushioning material. Shipping work was carried out efficiently and happily by members of the development team and logistic staff at the NAOJ Chile Observatory.

Receivers loaded on a carrier’s truck. These receivers will fly to Chile and will be delivered to the ALMA Operations Support Facility (OSF) at 2900 m asl, where they will go through further performance tests before being installed into the antenna.
