Two is better than one! When constructing and testing, it is crucial to construct multiple copies of components to allow for rigorous testing. Pictured here are two pressure vessels that enclose the radiation detector system. One test that the pressure vessels will undergo is a leak test to ensure that it can keep the gas inside at the appropriate pressure without leaking.
It is absolutely amazing to see designs come to life! This pressure vessel was designed completely by our team members, and here it is fully machined and welded. This pressure vessel will hold the tissue equivalent gas of our radiation detection system, and keep it under appropriate pressure to behave under radiation stress just like a human cell.
Yesterday NEUDOSE team member Erica had the pleasure of presenting the work done by our satellite team at the Quarterly Nuclear Energy Session for Natural Resources Canada. The group of government officials and industry executives were impressed with our team's progress. It was incredible to hear praise from such well established professionals in the nuclear industry! Pictured here are Colin Hoult (left), Deputy Director of Nuclear Strategic Policy for Natural Resources Canada, Diane Cameron (center), Director of the Nuclear Energy Division of Natural Resources Canada, and Erica (right) with our satellite.
Last week members from the McMaster NEUDOSE team spent the day with high school students to talk about our satellite project. More than 1,500 students, teachers, and mentors attended the FIRST Robotics Competition, hosted at McMaster University for the first time. Team members Mitchell, an engineering physics student, and Michael, a mechanical engineering student, were very engaging as they spoke with bright young students interested in science and engineering.
Do you or someone you know want to join the McMaster NEUDOSE team? We are recruiting! We are looking for some fresh new faces to join our exciting project! For information pertaining to recruitment, please visit our Recruitment page here!
Here is a close-up of the process of crimping the anode wire of the Tissue Equivalent Proportional Counter (TEPC). This anode wire collects charge from when radiation ionizes the gas that fills the TEPC. This technique is the primary method of radiation detection in our instrument.
Eric and Bhavesh are using two different microscopes to solder small components on circuit boards for the Anti-Coincidence Detector (ACD). The use of microscopes is necessary since the components are very small. There are approximately 400 different components on the small 9.3cm x 9.3cm circuit board. This work definitely requires an eye for detail!
The McMaster Nuclear Reactor has been graciously supporting McMaster NEUDOSE in many ways! The MNR has allowed NEUDOSE to test various electronic components and the radiation detector system inside of the reactor. We will be able to utilize many different sources of radiation, including gamma ray sources and the neutrons from the reactor core. Access to such a varied suite of scientific tools provided by the facility will prove to be an incredible opportunity.
MNR has also featured NEUDOSE on its website! We attended the Canadian Nuclear Association Conference last month with members of the MNR. To see the article, click here or on the logo below.
Pictured here is a 3D rendering of the data acquisition board from the Tissue Equivalent Proportional Counter (TEPC). The TEPC will collect charge from radiation as it ionizes a gas filled cavity. The TEPC is a major component of the on-board radiation detection system.
Last month we showed you the design of the mechanism that will deploy the solar panels of the satellite to collect energy from the sun. Well, here it is fully constructed! This circuit will draw electricity from the on-board battery to burn through the wire holding the solar panels closed. This will allow the solar panels to open using the stored energy in the springs and hinges.
