PHYS1630: Thermal Control Systems
(2018 Fall)

Course Description

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.

Evaluation ...

Two midterm examinations, totalling 60%, as follows ...

Term test #1 on 2018/11/02 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 2018/12/14 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 Notes and References

Laboratory Assignments

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.

Lab 1: PID Control

The tuning of PID controllers is examined - in this case the use of an ILX-5910C controller to accurately control the temperature of a KTP laser SHG.

Lab 2: Heatsinks

The characteristics and formulae around the use of heatsinks is examined.
