Mar 2016 - I400 available with TNC connectors

The I400 four-channel electrometer combines sensitive current measurement with the ability to bias the signal measuring circuit up to 400 V relative to ground. This makes it suitable for reading out miniature ionization chambers. These chambers typically provide the signal on an electrode which must be a few hundred volts relative to ground to bias the chamber. This feature requires the use of triaxial signal connections to eliminate unwanted leakage currents in cables and connectors. Up to now the I400 has been supplied with 3-lug triaxial bayonet connectors. Customers may now request the widely-used TNC threaded triaxial connector. This allows direct connection of a wide range of proven dosimetry chambers.

Jan 2015 - 2D-sensing ionization chambers

Ionization chambers with pixel electrode patterns provide true two-dimensional beam profiles. Strip electrode chambers assume that the beam can be characterized by two orthogonal one-dimensional projections. However some beam behaviors such as inclined elliptical beams are not well-represented by the projections - a true two-dimensional imager provides more information.

Pyramid has introduced 2D imaging chambers for particle therapy isocenter diagnostic purposes (the PX-2) and for in-situ beam profile monitoring (the PX-3). The PX-2 is available in a telescope configuration that measures the position, shape, trajectory and divergence of a beam. The PX-3 provides one of the lowest possible water-equivalent thickness beam position monitors for the particle therapy market. Go to the Products page for more details.

June 2014 - C400 pulse counting detector controller supported by spec

spec from Certified Scientific Software (http://www.certif.com) is the most widely-used instrument control and data acquisition software for X-ray diffraction. The Pyramid C400 four-channel pulse-counting detector controller integrates wideband pulse discrimination, fast-scaling, high-voltage supplies, pre-amplifier power and several diagnostic features into a single unit. Pyramid has been delighted to work with Certified Scientific Software, with the result that the latest 6.02 release of spec now includes support for the C400 (spec C400 help notes).

The C400 is available to the synchrotron light source community through FMB-Oxford Ltd (http://www.fmb-oxford.com).

April 2014 - New ionization chambers
The IC128-25 and IC64-16 ionization chambers for particle therapy are joined by the IC16-5. This compact chamber is intended for use upstream of a beam scanning system, where it continuously monitors the beam current, shape and position. Use of laser-machined thin-film electrode technology ensures the smallest possible amount of beam energy loss and scattering. Like its larger stable-mates, the IC16-5 includes environmental sensors for atmospheric pressure compensation, desiccant cartridge for de-humidification and hermetic sealing to permit its use with flow through gas if required. It has small anode-cathode gaps to allow operation at high beam currents with minimal loss due to recombination.

March 2014 - H20 two-channel magnetic field measurement system now available
The launch of the H20 two-channel Hall probe system provides a compact, high performance magnetic field measurement system that is particularly suited to particle beamlines, especially two-axis magnetic scanners. The matching MFP-30 probe is thin but rigid, and has design features that make it well-suited to the measurement of DC and AC fields up to several kHz, and good resistance to background neutron and gamma radiation.

The state of the art Hall element has low inherent noise and temperature coefficient. The use of a high stability current source, on-board digitization and downsampling, temperature measurement at the probe tip and full temperature compensation gives excellent low noise performance and high stability.

November 2013 - EPICS connectivity
EPICS (http://www.aps.anl.gov/epics/) is "a set of Open Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as a particle accelerators, telescopes and other large scientific experiments." Once data and controls for a device are available as process variables in the EPICS environment, then they can be accessed by a wide variety of client systems, including programs written in C++, C#, Java, Python, LabView™, Matlab™ and others.

Pyramid has released an EPICS connection for its products using the EPICS Channel Access Server, embedded in the Pyramid IG2 program. The IG2 service runs on any suitable host machine on the network to make all the defined devices and their process variables available to your client application, which can be running anywhere else on the network. Any Pyramid product that can communicate over Ethernet, either directly, or via a fiber optic loop controller, can be connected to EPICS this way.

The rich variety of applications in the EPICS community includes help for non-programmers too. Control System Studio (http://controlsystemstudio.github.io/) allows the rapid development of quite sophisticated user interfaces in very short time. As an example, the user interface for the F460 and M10 products shown below was created and debugged in the CSS BOY editor in less than one day.

May 2013 - Ionization chambers for particle therapy

IC64-16IC128-25BPM16-38
Pyramid is shipping ionization chamber products to customers who are setting the pace in particle therapy. The new IC64-16 chamber has joined the IC128-25 and BPM16-38 in our product range. The IC64-16 and IC128-25 set new standards for accuracy and resolution, while producing very low beam scattering. The BPM16-38 together with the industry standard I3200 electrometer is a reliable and robust solution for beam transport line tuning.
