The system is classified as a Grade B instrument, and operation can be carried out by the individual making the reservation or by qualified personnel.

2. 申請委託操作者須事先與儀器管理員連絡並進行實驗討論評估，確認試片規格是否合乎規範，並由管理員估價計算費用後，經指導教授或主管同意後，方可提出申請。
Those applying for commissioned operation should discuss and evaluate the experiment with the instrument administrator in advance, ensuring that the samples are suited for the instrument. The application can be filed after the cost is estimated by the administrator and approved by either the advisor or the supervisor.

3. 委託操作申請者請先至本中心網站下載『Hall實驗申請單』，詳填資訊後，e-mail至cnst-adm@cc.nctu.edu.tw並以E-mail向儀器負責人洽詢使用時段及確認實驗條件與試片製備。委託申請人需在現場共同進行實驗。
Each case of commissioned operation is by reservation only. Applicants who have been evaluated and approved can down the “Hall application form” from our website, and email the completed form to cnst-adm@cc.nctu.edu.tw. The applicants are required to contact the instrument supervisor via phone or email regarding the available time slot, sample preparation and fabrication. The applicants have to be present for the duration of the experiment.

4. 申請自行操作者，可於與儀器負責人連絡並進行實驗討論評估，確認試片規格是否合乎規範，經指導教授或主管同意後，始可申請加入本中心會員並提出自行操作訓練考核申請，其訓練考核程序請參照『六、自行操作訓練與考核辦法』，通過考核後始可自行操作。
The applicant who is willing to operate the instrument by himself should discuss the details of his experiment, such as sample confirmation and fabrication, with the administrator first. After obtaining permission from the supervisor, the applicant can apply for membership of the center as well as evaluation of operation and training. For details about evaluation procedures, please refer to “VI. Guideline for independent operation and evaluation.” Those who pass the evaluation can operate the instrument independently.

5. 自行操作者採取網路預約。通過機台考核之合格使用者始可取得網路預約之帳號。加入會員及申請訓練者請先至本中心網站下載『Confocal實驗申請單』，詳填資訊後，e-mail至cnst-adm@cc.nctu.edu.tw並以E-mail與儀器負責人洽詢訓練考核相關事宜。
The qualified users can make reservations online. After passing the practical evaluation, users can obtain an account number for online reservation purpose. Those who wish to apply for membership and training, please download the “Confocal application form” from our website. Email the completed form to cnst-adm@cc.nctu.edu.tw. Users should contact the instrument supervisor via email for details regarding training and evaluation.

6. 使用者須遵守實驗室所有相關規定。違反實驗室規定者依本中心實驗室管理規則辦理。
Users must abide by the regulations of the laboratory. Those in violation of lab regulations are subject to punishments accordingly.

7.。如有任何疑問，歡迎來信洽詢儀器負責人員。
Please feel free to contact the instrument supervisor for any further inquiries.

8. 機台使用費用規定請參照『收費標準』。
Please refer to “Fee” for details of fees for using the instrument.
