PHYS1630: Thermal Control Systems
In this course, students will study systems designed for management of heat in photonic systems. Control systems will be examined from simple 'bang-bang' control to PID controllers. Heat removal will then be examined including the use of heatsinks, Peltier-effect TECs, and water cooling. In each case, mathematical formulae will be used to predict systemn parameters.
It is required that you have obtained credit in PHTN1400 Principles of Laser Systems to enter this course since it involved the use of class IIIB and IV lasers and the prerequisite safety material was covered in PHTN1400.
This course is offered as part of the Photonics Engineering Technology (3 year) Program at Niagara College.
Two midterm examinations, totalling 60%, as follows ...
Term test #1 on Thursday 2019/10/31 in class
Covers thermal control methods and algorithms ranging from 'bang bang' to PID controls. Also covered is the use of heatsinks (including calculations of temperature and thermal resistance).
Term test #2 on Thursday 2019/12/12 in class
Covers the use of heatsinks, thermoelectric Peltier-effect coolers (TECs) and water cooling.
Labs and assignments combined for a total of 40%
Course Policies ...
Course policies follow the Standardized Policies and Procedures for CEE (dated January 2011). In summary:
- LATE assignments are worth ZERO. There is no "grace period" with a "per day" penalty. Late submissions (i.e. ANY not printed and ready when you enter the lab) receive a mark of zero. You will be DENIED access to the printer at the start of the lab - either the lab is ready to submit, or it is late and hence worth zero.
- Students are allowed only ONE single-day late submission without penalty. This is a once only one-day extension ... once used, any further late submission will receive an automatic zero.
(This policy reflects expectations in the real world: to be late for work, once, will likely not result in termination however chronic late arrivals will almost certainly result in job loss. Develop good work ethic _now_.)
- Students must pass the theory (testing) and practical (lab/assignment) portions of the course separately in order to receive a passing grade. If a failing grade is received in either portion, then the lower of the two marks (theory or practical) will become the final grade.
- In order to be considered for supplementary evaluation (SE) upon failure in this course, a mark of 50% minimum will be required in the practical (lab/assignment) portion of the course plus a mark of 45% minimum in the theory (testing) portion. A theory mark of 44% or less, or a lab mark of 49% or less, will result in failure with no SE option.
- Granting of an SE is not automatic - those qualifying for an SE must apply to the chair who will arrange for the SE (since staff must be assigned to deliver the SE). Attendance and lab performance will be considered.
- Devices capable of RF reception are specifically banned during all examinations and tests. This includes cell phones (which are not permitted, whether turned on or not) as well as tablets and laptops. Scientific calculators must not have RF capability (i.e. the use of a cell phone, tablet, or laptop as a calculator is expressly forbidden even if the "wireless" function is switched off). Translational references and dictionaries must be in paper form, not on an electronic device.
Complete course policies can be found in the Teaching and Learning Plan (T&LP) document found on Blackboard.
There is no text for this course. Notes and Web links will be provided as the term progresses.
Course Notes and References
There are several labs and assignments in this course. Lab sessions are two-hours in length.
In line with departmental policies, the lab/assignment portion of this course MUST be passed SEPARATELY from the theory portion in order to pass this course. Late labs result in an immediate mark of ZERO with no exceptions and no excuses accepted (including the now infamous "my printer ran out of ink" and "my computer died"). Failure to submit a lab (and a late lab is considered failed and will receive a mark of zero) will result in the student being placed on course condition. Failure to submit a second lab results in immediate EXPULSION from the course.
