Help me translate this phrase

[amaravati]

かんっぜんにおこったビーム
Does anybody knows what this phrase means?

[kempokatt]

I'm not that good but...

I think it says something like:

The beam is working perfectly.

<OR>

The beam has started working.

[Harisenbon]

well, it has been entered wrong, but like kempokatt says, it says that "It is a Laser Beam that works perfectly." It's a noun phrase, so I assume it's part of a larger sentence.

it should be

かんぜんに　おこった　ビーム
完全に起こったビーム

[amaravati]

I didn't know that the phase was incorrectly written, because I copied it from a japanese website. What does the particle に doing after the word perfectly in the sentence exactly?
I understand that you use it to indicate time, location, direction, and indirect object. Do you use it to indicate adverbs as well? Can anybody give me any other example(s) of how to use ni in sentence with similar structure as I mentioned

[Harisenbon]

You can also use に for certain adverbs as well as nouns used as adverbs.

Some examples would be

早めに駅に行ったほうがいい
You had better go to the train station quickly
