The XIII Scientific Meeting of the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will be held in Teruel, in the headquarters of the Centro de Estudios de Física del Cosmos de Aragón (CEFCA) between the 5th and 9th September. This meeting, which is part of a series of meetings usually celebrated twice a year, expects the attendance of about 70 professional astronomers both from Spain and foreigners.
After passing the verification tests, the cryogenic camera is being prepared to be delivered at CEFCA next August.
The aluminizing vacuum chamber and the cleaning unit for the maintenance of JST250 and JAST80 telescope's mirrors arrived yesterday at the Observatorio Astrofísico de Javalambre (OAJ). The chamber has been designed by CEFCA and Vacuum Technology Associates Inc, DYNAVAC (Boston, United States), responsible for its manufacture.

Optical fine tuning of the system during Final Acceptance tests provides images of 0.15” FWHM using “lucky imaging” techniques

CEFCA has proceeded with the final acceptance of the JST250 telescope installed at the Observatorio Astrofísico de Javalambre after carrying out additional tests with the verification camera in order to test proper operation of the telescope.

The OAJ already keeps the actuator system of JPCam in its clean room. After its arrival in mid January, the engineering team has carried out the integration of the system at the observatory in order to start with the verification and fine-tune processes, first in the clean room and, finally, in the JST250 telescope.

Achieved images of 0.33” PSF with “lucky imaging” techniques

Last September 2015, the JST250 telescope at the Observatorio Astrofísico de Javalambre passed successfully the Provisional Acceptance test review. This milestone represents a big step forward for the completion of the project, only pending the Final Acceptance tests that shall be completed in the next weeks.

In late September, responsible members of CEFCA and the J-PAS collaboration visited e2v headquarters to see, first hand, the progress made on the set up of the cryogenic camera of JPCam, the scientific instrument designed by CEFCA and Brazil for the JST250 telescope.
During the last months has been carried out the installation process of the main storage and processing systems for the UPAD/T250. The infrastructure has been provided and installed by the companies Bull España S.A. and Fujitsu Technologies Solutions S.A. These systems increase the already existing capabilities of the UPAD/T80 in order to deal with the huge amount of data produced by JPCam once the camera is installed at JST250 telescope.
With the successful achievement of this important milestone, e2v has demonstrated that the focal plane is well within the very strict JPCam requirements. The JPCam engineering focal plane has been successfully integrated at e2v (Chelmsford, UK). JPCam, the main scientific instrument of the JST250 telescope, is a 1.2 Gpixel camera designed to perform the J-PAS survey.
With the declaration of the OAJ (CEFCA's observatory) as ICTS, the center has received a recognition for its scientific, tecnological and innovative competitiveness and quality in the Spanish R&D system.
In September 25th, at 22:57h Local Time, the Javalambre Survey Telescope (JST250) achieved engineering first light. This is a very important milestone in the project since it is the first time that photons from the Universe, in this case coming from the Polaris star, have gone through the complete optical system of the telescope as it was designed.
JST / T250 telescope of the Observatorio Astrofísico de Javalambre (OAJ) was completely integrated on September 2, 2014. The integration of the telescope with the final optical elements was made after a previous test phase in which the mechanical and control parts of the telescope were verified with dummies instead of the real optical elements.
The assembly of the main telescope of the Observatorio Astrofísico de Javalambre (OAJ) is one of the most important milestones of the project. The first structural pieces of the JST / T250 arrived last month, and now they have begun to settle in the Observatorio Astrofísico de Javalambre.
The dome of the building that will contain the JST / T250 telescope of the Observatorio Astrofísico de Javalambre has been installed this week. This operation was done once the performance and sealing tests were successfully conducted.
The JST250 telescope has passed the first test of general operation that was conducted this week at the headquarters of the Belgian company AMOS, responsible for the construction of the telescope. This is the first phase for the preliminary acceptance of the telescope.
