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!
Anode Wire Crimping
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.
Soldering On
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!
McMaster Nuclear Reactor Support NEUDOSE
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.
TEPC Data Acquisition Board
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.
Constructed Solar Panel Deployment Mechanism
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.
X-Ray of the Command & Data Handing Circuit Board
Soldering is the technique used to connect different electrical components on a circuit board. When it comes to connecting small components, it can get quite tricky. The entire circuit board for the command and data handling system, which processes information on-board the satellite, is 9cm x 9cm. This means all of the components are very small! To ensure the greatest quality for all connections on the circuit board, an x-ray was taken to look for defects. The captured x-ray is shown below. Proper quality assessment is crucial for all of our components - even the smallest ones!
Meeting Industry Professionals at CNA 2017
Last week at the Canadian Nuclear Association conference, McMaster NEUDOSE team members got the chance to meet with many executives in the nuclear industry. Two notable professionals that loved hearing about the satellite team and unique radiation detector system included Kim Rudd, MP and Parliamentary Secretary to the Minister of Natural Resources, pictured left, and Dr. Michael Binder, President of the Canadian Nuclear Safety Commission, pictured right. The kind words received by our team from such distinguished individuals was invigorating, and we look forward to sharing more of our progress in the future!

McMaster NEUDOSE at CNA 2017
Five students on the McMaster NEUDOSE team spent the past few days at the Canadian Nuclear Association's annual conference. Our team members were raising awareness for our project by speaking with professionals in the nuclear industry.

Solar Panel Burn Wire Mechanism
Pictured above is the printed circuit board for the burn wire mechanism for the electrical power subsystem. When the satellite is launched from the rocket, the solar panels will be closed and tethered shut to protect from damage during initial tumbling. Once the satellite is stable, this mechanism will activate to release the solar panels outwards to allow for light collection. This is crucial since the solar panels will utilize this light to produce electricity for the entire satellite!
