Nuclear Imaging Research using Acrylic Vacuum Chamber

Nuclear imaging is quickly becoming more and more sophisticated and images unimaginable twenty years ago are become reality – think about the recent image of a single atom. Nuclear imaging is detection is a highly technological field.

A nuclear scintillator converts gamma rays which are invisible to the naked eye into electrical signals and enables the researcher to detect the energy of the gamma ray as well as the intensity. They way it works is when a gamma ray crosses into the scintillon crystal, it will start interacting with the electron clouds of the crystal molecules. This interaction will slowly begin to slow the gamma ray down while at the same time emit photons in the visible light spectrum. Conversely, the higher the energy of the gamma photon the more photons are created. The visible photons as a result of the interaction between the gamma ray and the scintillator crystal are now picked up by the photocathode, amplified, and finally converted into an electric signal. This electric signal is then processed and converted into the Gamma Ray Energy enabling the experimenter to determine the energy of the gamma ray. The result is a graph of the gamma ray energy spectrum.

In addition to being able to better detect gamma rays and quantify its energy level, better nuclear imagining becomes possible as well since the X-Rays are detected better, less X-Ray intensity is needed to yield same quality image. The fortunate result is that the patient does not need to be exposed to as much radiation leading to better treatment outcomes.

Our client was not able to tell us exactly what they were doing since their research is top secret and proprietary. This is what they told us: “The vacuum chambers are working out very well for us! We used those devices to improve one of our analytical methods and have experienced no problems at all with their functionality. We are very happy with them…”

We built a total of 9 of these Acrylic Vacuum Chambers for them. This our spring supported top load model. The lid is supported with a gas spring that keep the lid open in order to the end user to load the chamber without having to worry of slamming the lid down. In addition, we added two stainless steel drain valves on the bottom wall. The valves are elbowed and are facing out towards the sides. As a result, we had to raise the chamber up in order to provide clearance so we added a skirt.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Digital Vacuum Gauge Instruments
A Digital Vacuum Gauge is an instrument which precisely measures a vacuum level inside a vacuum chamber. Unlike a rough dial vacuum gauge, which shows only where the vacuum chamber is roughly with an error of up to 3% (a high as 1 inHg) a digital vacuum gauge will show vacuum levels up to 3 significant figure in Torr and millitorr – this makes the digital vacuum gauge ten thousand times more accurate than the dial vacuum gauge.
Our Work: Custom Vacuum Chamber with Blank Plate
You are looking at our standard Acrylic Vacuum Chamber, Hinged Door with Clamps. There is only one difference; this vacuum chamber has a blank acrylic plate that is connected to and aluminum plate which in turn is anchored to the side wall of the acrylic vacuum chamber. This blank plate is there to enable our client to add vacuum feedthroughs to the side wall in the future

How do you know that you have a good part during your leak test? In order to understand your leak test, you must first understand the Test Decay Curve and what it tells you about your test specimen. There is a certain way that a test specimen behaves during the leak test.
