Physics main Jacob Sichlau ’23 interned this summer time at Varian Clinical Programs on the microwave ablation group. The working experience verified his interest in pursuing a master’s degree in mechanical engineering soon after Hamilton.
What is microwave ablation?
Microwave ablation is the use of microwave radiation (frequencies amongst 300 Mhz and 300 Ghz) to ablate tumors inside of the body. The stop of the ablation probe (mainly a 20 cm lengthy needle with a transmitter near the finish) “cooks” the surrounding tissue, ideally encompassing the tumor with a spherical ablation space.
Did you appear to Hamilton intending to main in physics?
I did strategy on studying physics on a route toward engineering. Absolutely nothing has derailed that class, but Physics 190 with Professor Gordon Jones solidified my motivation to remain within just physics.
Did you have other activities at Hamilton this sort of as investigation or other internships that served put you on this route?
I in fact sought this internship out because of the deficiency of overlap with do the job I have carried out at Hamilton. Figuring out that I want to go into mechanical engineering, I preferred an chance to establish some of the much more technical engineering expertise right before coming into a graduate system. Even so, much of the work I did included 3D printing prototype parts, a thing that I had a very good little bit of experience from operating a particular small business just before I arrived to Hamilton.
Hamilton features quite a few twin degree plans (B.A. from Hamilton and B.S. from the engineering college) for college students intrigued in engineering but who also want the benefits of a liberal arts instruction.
What were being your duties at Varian?
My biggest activity was developing custom pieces to keep the antennas and specimens in the bath. I was in charge of developing a wide array of 3D printed elements that can examination a variety of characteristics of the device and other smaller sections. The largest of these apparatuses was to affix the ablation probe above a temperature-controlled bathtub in which the ablation take a look at specimens are held. This take a look at equipment is intended to test the qualitative functionality of the device. An additional apparatus was supposed to give a quantitative analysis of the probe functionality with the S11 measurement. The S11 measurement checks how significantly of the microwave sign is mirrored back again into the probe, which also implies the efficiency of the sign emitting procedure of the probe. At last, there were a couple other smaller sized components to check pull-apart energy for magnets, store compact pieces, and so forth.
I sourced elements to test Varian’s most recent microwave ablation machine. The testing is composed of holding bovine organ samples in a temperature-managed bath and inserting the ablation antenna to consider its performance. I sourced the organs, thermometers, and numerous other odds-and-finishes for the screening apparatus.
I (also) labored on screening the resistance of fiberglass tubes that sort the entire body of the ablation antenna to internal tension buildup. This associated standardizing the exam course of action amongst three distinctive sites (Austin, Minneapolis, and Galway, Eire) and then assessing the tube failures to establish the probable hazard to the item and affected person.
(I also contributed to) revision of the emitting section of the antenna to make the assembly process simpler and enhance the overall energy of the ablation antenna. I served model and examine a person of the potential options, portions of which were applied into the system.
What did you master this summer season? About the issue, about your self?
A great deal of my understanding was quite technological, but I also figured out a great offer about how the engineering approach operates in marketplace. Some of that was seriously exciting to see, like the layout evaluate procedure and the brainstorming that takes place when a challenge is identified. Even so, some other pieces weren’t as fun, like the paperwork that goes into company top quality specifications and Fda laws. I’m glad to have observed both these sides ahead of thoroughly commencing my profession, but my premier takeaway is that I appreciate the highs a great deal more than I dislike the lows.
Did this internship enhance your ideas to go on for a master’s in mechanical engineering?
Sure, prior to this internship I was contemplating a number of other fields of engineering for a master’s, but I asked for a ton of guidance from my coworkers and the resounding solution was that it was greatest for me to go after a master’s in ME. Not only does it greatest align with the engineering tasks I love most, but it is also an very adaptable diploma that can guide to a vast selection of fields and roles.
