Illustration of the HiSCORE detector.

HiSCORE stands for Hundred Square-km Cosmic ORigin Explorer. Our goal is the investigation of the accelerator sky with observations of gamma-rays in the so far poorly covered energy range above 10 TeV (Ultra high energies) and cosmic rays at energies from 100 TeV to 1 EeV. Our main motivation is the search for cosmic ray pevatrons to solve the mystery of the origin of cosmic rays, going in energy ranges where no experiment has been before. We plan to build a small engineering array (order of 1 square-km) in the Tunka valley (see news HRJRG and Tunka field trip) in cooperation with collegues from the Moscow and Irkutsk State Universities. Further deployement is planned on the Auger site in Argentina.

3 HiSCORE stations were deployed in October 2012 at the Tunka site. Data taking and component testing is underway over the winter season 2012/2013. The picture shows the deployment team in front of station number 3 (large box with red cover) and its electronic box.

First Prototype installed on Tunka site
25.04.2012


Cherenkov light pulses from channels A and B of the first on-site HiSCORE station, and the Tunka channel used for trigger.

During our Tunka expedition from 7th of April to 15th of April, we successfully installed a prototype HiSCORE station on the Tunka site. We took data using the Tunka DAQ system and saw first Cherenkov light flashes. With these data, we plan to perform a first HiSCORE-Tunka cross-calibration study. This expedition also was very useful for understanding some details about our concept and for initiating improvements. Thanks to everybody involved !

Joint efforts with Russian (Inst. Nucl. Res. Russian Academy of Sciences, Appl. Phys. Inst of Irkutsk State Univ., Moscow State Univ.) and German institutes (DESY, KIT, UniHH) are now supported by the Helmholtzgemeinschaft with a HRJRG grant ! Also see DESY press release. A web site for our new HRJRG is in preparation.

First Tunka field trip successful

A Tunka cluster box, which will also serve for integration of the first HiSCORE prototype on site.

From 17.10.2011 to 24.10.2011, our first field trip to the site of the Tunka experiment took place. We have successfully integrated a station PC (guru plug PC) to the Tunka network and integrated it to the Tunka DAQ. A server/client connection is active and ready to be used for HiSCORE station control at the Tunka site! In the coming months, deployment of a prototype station in the Tunka valley is planned.

First 2-channel station prototype

The 2-channel prototype station.

The first prototype station consisting of 2 PMT channels with Winston cones was assembled and fully equipped with electronics. First tests yield positive results. We are currently working on iterating the station components, using our test experience as input.

Helmholtz Alliance for astroparticle physics granted !

HiSCORE is now supported within this alliance (HAP) with 1/2 PostDoc and one PhD. We plan the deployment of prototypes at the Pierre Auger observatory and studies of combination of HiSCORE with Auger.

NSB measurement from Fowler's Gap published
11.05.2011

The research station Fowler's Gap in New South Wales, Australia, is being discussed as possible site for HiSCORE. Evaluation of the site is ongoing. In two campaigns in February and August 2010 the night sky brightness at the site was being examined. The results are now accepted for publication in "Advances in Space Research". The paper can be found on the ArXiv and in our Document section .

TEXAS Proceeding paper on HiSCORE
20.04.2011

The proceeding paper to the TEXAS 2010 conference in Heidelberg with the title "Simulation of the expected performance for the proposed gamma-ray detector HiSCORE" has been accepted for publication in Proceedings of Science. Currently, it can be found on our website (here) and on the ArXiv. It gives a round-up of the HiSCORE project and its status and explores some possibilities to decrease the energy threshold.

History

This project was initiated by us in Spring 2008 with the goal of investigating the gamma-ray and Cosmic-ray sky (accelerator-sky) in the energy range from 100 TeV (TeV = Tera-electron-Volt) to 1 EeV (EeV = Exa-electron-Volt). A few physics questions motivating such a detector are addressed in our Physics section and in our publications.
One of the key components of the project is the development of a new detector, which is described in some detail in the Detector section.

The HiSCORE project is part of the Astroparticle Group by Prof. Dr. Dieter Horns at the University of Hamburg.
