Custom Design detectors - Series CD

Canberra received the 2006 ALICE Industrial Award from the CERN Nuclear Research Centre for achievements in the production of silicon detectors.

Canberra received a Group Achievment Award from NASA for its part in the RAD system aboard the Mars Rover.

PEPSSI (Pluto Energetic Particle Spectrometer Science Investigation)

The New Horizons spacecraft carries the PEPSSI instrument, a spectrometer designed to detect electrons and ions in the 30 keV – 1 MeV energy range. A total of 54 CANBERRA detectors are flying on three different missions!

With CANBERRA, customers can expect:

We Design and Build Silicon Detectors To Your Requirements

The photolithographic process which is used to define device geometries allows CANBERRA to fabricate detectors of virtually any shape mounted on PCB, ceramic or customer specific support. The ion-implantation process lends itself to the production of strips or resistive contacts which make possible position sensitive detectors.

CANBERRA received the 2006 ALICE Industrial Award from the CERN Nuclear Research Centre for achievements in the production of silicon detectors.

Canberra’s strengths:
  • World leader in novel technologies
  • Strong knowledge in harsh environments: under water, outer space, corrosive, other planets
  • More than 3 decades of experience
  • Simulation of detector operation using dedicated software packages
  • Full in-house processing
  • The good characteristics as with the standard PIPS detectors are maintained in the custom design detectors: low leakage current, thin entrance window, good resolution
  • Open communication and pro-active response

PEPSSI (Pluto Energetic Particle Spectrometer Science Investigation)

The New Horizons spacecraft carries the PEPSSI instrument, a spectrometer designed to detect electrons and ions in the 30 keV – 1 MeV energy range. One of the aims of the PEPSSI team (located at the Johns Hopkins University Applied Physics Laboratory) is to study the interaction between the Pluto system and the solar wind by detecting neutral particles from Pluto’s atmosphere that are ionized by the Sun’s light and then picked up and accelerated by the electromagnetic field of the ~1.5 million km/hour solar wind. A total of 54 CANBERRA detectors are flying on three different missions!

CASSINI

Launched in on Oct. 15, 1997, Cassini's mission to explore Saturn ended on Sept. 15, 2017 with a deliberate plunge into Saturn's atmosphere. The spacecraft collected and transmitted data until the very last seconds of the mission.

Mirion Technologies supplied the custom design PIPS detectors integrated in the MIMI LEMMS and CHEMS sensors. They detected energetic charged particles (protons, electrons, ions) in the excited gas, or plasma, around Saturn.

  • The Low-Energy Magnetospheric Measurement System, known as LEMMS, measured the number of electrons, protons and ions that struck its detectors, as well as how fast they were traveling and what directions they were coming from. 
  • The Charge-Energy-Mass Spectrometer, called CHEMS, measured the charge and composition of the particles that struck its detectors. Each particle’s mass tells scientists what element it is, for example, whether it's a proton or a “water group” ion such as H2O+.

 

Besides presence in this spacecraft, PIPS detectors are deployed on the following current or recent missions; STEREO and DOUBLE STAR studying solar storms, MESSENGER studied Mercury, NEW HORIZONS (passed Pluto to outer space in a second extended mission), MSL RAD exploring Mars, JUNO exploring Jupiter...

Customer Testimony:

“I was extremely happy working with this team. In our initial design we frequently met by phone and worked through different options. They provided excellent suggestions, and together we came up with the best solution. They were available to meet with very little notice, had excellent technical expertise, and kept the effort moving on or ahead of schedule.“

Single and Multi-Element PIPS (SMEPS) detectors - Series RF, PF

As a result of CANBERRA's extensive work in Custom Design PIPS Detectors a number of these detectors, called SMEPS Detectors, are available at modest cost without a tooling charge. The Single Element PIPSDetectors are subdivided as one dimensional position sensitive detectors (resistive charge sharing over the implanted junction) and standard rectangular elements.

The Multi-element PIPS Detectors are subdivided into standard pad detectors, thin window pad detectors (<50 nm) and two dimensional position sensitive detectors. These detectors are generally mounted and wire bonded to an epoxy board or a ceramic board for the ease of use.
