Cosmic Gun: Detect Gamma Radiation

Hours: 12:00PM-3:00PM
Cost: FREE


With some generous support from the Arts Development Fund of the Home Affairs Bureau, the Government of the Hong Kong Special Administrative Region, we are able to offer free registration for this event!  Please RSVP at the link above.

Build your own Cosmic Gun, or custom cosmic ray detector.  Cosmic Gun, the device art, is an amateur, low-cost astronomy project that enables the general public to be connected momentarily with cosmic rays coming from outside the Solar System.

The metaphor of contacting cosmic rays is far more than literally interpreted, the poetics of this project built upon the notion that ‘The Solar System belongs to everyone on this planet, any authorities aim for taking this fundamental rights away is brutally attacking our beliefs on human rights as a global citizen.’

The workshop will introduce different cosmic rays detectors inventions around the globe and hands-on technical skills on building DIY cosmic rays detectors.

The participants will build an experimental low-cost photo diode radiation detection circuit using a humble photodiode (BPW34) as a major component.  This is an alternative to the Geiger-Müller tube (GM Tubes); while they are the most common way to detect radiation, they are both widely inaccessible and expensive.

Annie Wan is an international media artist, often creates artworks focus on relationships between spaces and sites, materials and immaterial. Her works have been exhibited in festivals in Europe, Asia and North America, including Art+Communication Festival 2004 (Riga, Latvia), Multimedia Art Asia Pacific Conference 2004 (Singapore), ZeroOne/ ISEA 2006 (San Jose, United States), French Pavilion in 10th Venice Architecture Biennale (Venice, Italy), Ogaki Biennale 2010 (Ogaki, Japan), Hong Kong Contemporary Art Awards 2012 (Hong Kong, China) and International Festival of Creativity, Innovation & Digital Culture (Canary Islands, Spain).


This workshop project is supported by the Arts Development Fund of the Home Affairs Bureau, the Government of the Hong Kong Special Administrative Region.  Cosmic Gun is originally commissioned by New Vision Arts Festival 2014, Leisure and Cultural Services Department, the Government of the Hong Kong Special Administrative Region.
