I would like to know where the maximum size for each experiment is defined. Can I define it?

Default maximum collection size setting is 12 Mb.
You could check if it was altered in your system in the database package DOCUMENT_CELL in the procedure SAVE, is the following code:

-- Test for a total size of 16 megabytes, and report that the total size is greater than 12MB to account for the
-- expansion caused by base64 encoding of the data.
IF (totalSize > 16 * 1024 * 1024 ) THEN
RAISE_APPLICATION_ERROR(-20000, 'the total size for documents in this collection (' || (totalSize * 3 / 4) || ') is greater than 12MB');
END IF;

Correspondingly, max collection size is 3/4 of 16 -> 12 Mb.

Mentioned DB procedure collection size check / limitation is related to MS Office + PDF sections only, otherwise there is no size check, and no limitations.
However, PKI does not recommend having collections over 50 Mb of total size as it could result in performance issues, and recommends using SDM for big files.
