As advocate, in my opinion the proposal looks good, and the application of SCr's in Power Electronics undoubtedly had a major impact in the whole world. An open issue is where to mount the plaque, as the original building seems neither available nor much significant in the whole process of development, introduction and manufacture of SCR's by GE. It would be useful to the Committee if the proposers elaborate in the argumentation why Schnectady and in particular the Museum is appropriate.

Dear Juan, I have received approval from AA Technologies to mount the plaque on the outside of the building and I have received permission from the Rochester Section to host the plaque in their section.
I cannot access the proposal to update the changes, perhaps you can guide me on that.

The conditions have been met, and three distinguished professors have expressed their full support for an IEEE milestone dedicated to the SCR. This invention and its applications, changed completely the Field of Power Electronics, worldwide, and deserve an IEEE Milestone.
As said before, there is the issue of the best place for the plaque. The original proposal was in Schnectady, at the Museum of Innovation & Science. This city was an important site for General Electric, and became associated to the SCR because from there the main business of SCR was conducted for years. That’s the reason for the original suggested place for the plaque.
It was pointed out that a museum, per se, is not necessarily the best place for a plaque unless there is a strong connection with the subject of the Milestone; the development of the first SCR was made in Clyde, a 2000 persons village a few hundred miles away. So the proposers obtained another authorization letter to place the plaque in Clyde -, where the original work took place, in a building now belonging to another company. I’m afraid nobody will ever see this milestone’s plaque, “in the middle of nowhere” [ just look at the place in google maps ]
In my opinion the museum in Schnectady is a much better option, first because the name of Schenectady is strongly associated with the SCR Technology, and second for the much better public visibility. We have two letters of authorization, two possible places. What is the feeling of the Committee? Which is the best place?

The SRC is definitely an important milestone for power semiconductor devices.

The SCR is truly deserving as an IEEE Milestone. I read the proposal. I have 4 specific minor changes on the modified citation below. [ the citation has already been adjusted ]

I support the proposal to include the SCR / thyristor as a IEEE Milestone. Furthermore, I also would like to express my complete agreement with the proposal´s rationale as stated in the full proposal, comprising the historical and technological significance, the difficulties that had to be overcome and the singularities of the device. The thyristor has been in the basis of modern electric power management by electronic means and its creation and development deserves a special tribute. I also agree with the proposal on mounting the milestone plaque at a Museum in Schenectady, NY. Schenectady is the location from where GE and its joint venture with other companies have developed and commercialized thyristors and other power semiconductors.

Review of Milestone -- Jason.k.hui (talk) 14:45, 2 October 2018 (UTC)
I support the Milestone. I noticed there's quite a usage of parentheses in the citation. Possible suggestions to tightened up the citation are:
1) Remove "GE" as General Electric is only used once
2) Since the title already has the words "Silicon Controlled Rectifier (SCR/Thyristor)," remove "silicon-controlled rectifier" in the citation and just use the words "SCR, later included in the thyristor family" without the parenthesis
3) Are the parentheses with acronyms absolutely necessary in the last sentence?
I support the milestone. I partially agree with deleting some of the parentheticals. I suggest simply deleting (GE), deleting the back of the SCR parenthetical (, later included in the thyristor family) and deleting (thyratrons). I would keep (TRIAC), (GTO), and (IGCT) since they are all terms of art. Dave Bart
