Sounds like it's technically possible but never really used in practice. Since daijisen has a "加速装置" sense and Marcus found some genuine usages in google books, I can't imagine that anyone will impugn us for keeping the "pedal" meaning as a third sense with a [rare] tag.

I would argue that koj and gakkoku say it's from アクセレーター (I included the others not as support for the change, just to give a fair summary). That plus the inclusion in Luminous plus the evidence of usage seems enough to include it. I'm sure we could find much more (old) usage on lab.ndl if we wanted too. I think it's fine.

The meaning of the first sense wasn't clear to me. Judging by the kokugos I think it's referring to things like graphics or cryptographic accelerators.

https://en.wikipedia.org/wiki/Cryptographic_accelerator

Daijirin displays "アクセレレーター," so probably better to make that [rk] rather than [sk].

The kokugos only tell us that アクセル is a shortening of アクセラレーター/accelerator. None of them have an accelerator pedal sense for アクセレレーター.
Looking at the n-grams, I don't think we need an accelerator pedal sense. To say it's "rare" is an understatement.

Re Hendrik's latest reference, it really confirms that 半波 is most likely an abbreviation of 半波長.
I'll close this one off, and propose an [abbr] entry for 半波.

After submitting my previous comment I found another reference, close in topic to the original reference, that highlights the second way of parsing 半波長:
https://ja.fmuser.net/content/?6795.html

LOL. I did not pay attention to the fact that 半波長 can be parsed 半+波長 in addition to 半波+長 (the latter is more obvious to me, since the use of 半波 in 半波長 is just one of several possible contexts in electrics and electronics, and 半波 by itself is "a thing" for us electronerds). A less ambiguous reference for my original submission would have been https://www.rohm.co.jp/electronics-basics/ac-dc-converters/acdc_what2 or https://kotobank.jp/word/半波電位-1578986. My suggestion is therefore to leave this entry as 半波, since we do have 波長 in the database already (on the other hand, I would not object to you adding both 半波 and 半波長 to the data base).

It's often used prenominally but I don't think it's adj-no. The 〜の n-gram terms aren't adjectival.

https://www.glossary.jp/sec/transaction/loop-trade.php
同一資金で銘柄を変えながら、1日に何度も取引を繰り返す取引のことで、日本の株取引においては、同一銘柄に関して、買い約定代金の合計が元本を超えて何度も現物取引の売買を繰り返すことは、差金決済に当たると考えられて禁止されていたが、2001年に金融ビッグバンの一環としてループトレードが解禁された。
